Girlfriend become aggressive when we bump into other women

This is really affecting our relationship and our lives, since she doesn't trust me to go alone to the supermarket anymore.

That is absurd. There likely is no way you can reason with someone who is so far gone she won't let you run ordinary errands. Unless she's willing to stop her accusations cold turkey, or get counseling to help her stop, this will not get better. Break up. In 6 months, you will wonder how you ever put up with someone who thought you were a filthy and disgusting wanna-be cheat for as long as you did.

To make everything worse each confrontation we have on the matter could easily escalate into verbal and physical violence,

I don't know how to get across to you how completely unacceptable that is. You cannot share your life with someone you sincerely think is going to be violent.

by making her understand that I'm not interested or attracted by other women

You cannot "make people understand" things like that. What you can do is, with your actions, show that you absolutely refuse to be treated like a cheating pile of garbage.

I'm just giving my personal story and what I did.

Problem: I had a immature girlfriend who constantly needed to be reassured she was the only one for me and like yours she would sometimes escalate things with shouting or hitting. This relationship only lasted a few months but I don't think this changes anything. No amount of reason or conversation worked and would cause an escalation or for her to ignore me.

Solution: Relationship was toxic so I called it off.

There is nothing you can do. She needs professional help to get over this self-esteem hurtle. You should not have someone who verbally and physically abuses you in your life and please don't use the length of relationship as an excuse.

You need to take care of you.

Wow. She's telling you what you're thinking, and punishing you for it. That's pretty much a definition of abuse, and when you add,

To make everything worse each confrontation we have on the matter could easily escalate into verbal and physical violence, so upon the next encounter I become visibly stressed, and her interpretation is that I'm trying my best to not fall for the other girl.

that clinches it. The dynamic for abusive relationships is bilateral low self-esteem.

One partner copes by abusing, the other by accepting abuse.

Every time this happens, ask yourself, "How long will it go on like this??" (Try it, right now.)

"How long will it go on like this??"

"How long will it go on like this??"

You cannot solve this on your own. Read stuff on the Gottman institute, but RUN, do not walk, to INDIVIDUAL therapy. Couples therapy in most abusive relationships just gets taken over by the abuser.

Once you understand your own role in this, you can think about whether this relationship can be salvaged. If you stay without fixing it, you will have a lifetime of useless misery.

A point one of the references made is that most abusers have personality disorders, which means they can't change their behavior. So the solution becomes individual therapy to help the abused one avoid abusive relationships, after they leave the one they're in.

Good luck, Jim.

We have often heard of the gender-reversed situation- a man telling a woman where she can look, what she can do, and where she can go so long as it's with him because he "doesn't trust her". What you've described is controlling-behavior and it's not part of a healthy relationship.

I've gone through each of your points, and while I found them very accommodating on your part- none of them addressed her behavior. All solutions addressed how you should respond to her controlling behavior. You have to address her behavior and set boundaries. I like scohe001's answer to "Set Boundaries". It's good to have boundaries, and I would add- have consequences if those boundaries are broken.

each confrontation we have on the matter could easily escalate into verbal and physical violence

I think the physical violence part is unacceptable. If you seek mutual-respect then neither of you should control or hit the other.

You can easily google "mutual respect in relationships" and research how important this is in relationships. Here is one definition from www.centersforfamilychange.com/relationship_problems_respect.htm:

Mutual respect is a very simple concept. It means that you treat your spouse or partner in a thoughtful and courteous way. It means that you avoid treating each other in rude and disrespectful ways, e.g., you do not engage in name calling, and do not insult or demean your spouse or partner.

That doesn't sound anything like what you described here unfortunately.

I would set a boundary that mutual respect is given and received- and apply it to your relationship. You can tell her directly or let her look up the definition herself. If mutual respect (the boundary) is broken- let there be a consequence (you decide what that is).

I want to add to breversa's answer that you don't have to hope the problem will resolve itself somehow and suffer her outbursts in the meantime. You can diffuse a situation by adressing her insecurities directly.

You can tell her that her accusations are unwarranted:

(She) Don't look at that girl!
(You) Huh? Which girl?
(She) The one you've been staring at who doesn't wear pants.
(You) Why would I look at her? I don't even like how she looks.
(She) You've been staring at her *ss.
(You) No, I've been staring at the dog behind her that I find rather cute.

You can reassure her that you aren't interested in these women:

(She) You'll leave me for one of those.
(You) But I don't want to leave you. I love you, not some superficial pretty face.
(She) I can't compete in this continuous "appearence competition" with other girls.
(You) You don't have to. I love you for your pretty smiles and big heart (or whatever you really love on her. Be honest here!)
(She) I don't believe you!
(You) I also love how you make me feel special / make me laugh / make me feel at home (again, be honest. Talk about your feelings towards her). No playboy poster girl could ever make me feel that way. You're the only one I feel this way with.

If everything else fails, a good strategy is to ask questions instead of declaring your innocense.

(She) You'll leave me for one of those.
(You) Why would I do that?
(She) because she's prettier than I am.
(You) Why do you think I would want to leave you for someone else?
(She) Because that's always how it goes.
(You) We've been in love for 5 years. Why do you assume I would run off with the first woman I see on the street?

That forces her to actually think about her feelings and reasons for her outbursts instead of just replaying the same old record again.

If you simply say "No I didn't look at any woman" she can just as simply declare that she doesn't believe you or that you lie. If you ask her instead why she thinks that you stared at anyone, she has to come up with a reason or at least a presumption. She might realize that there is no reason for her fear or she might confess her fears to you and then you can adress them directly and reassure her of your feelings for her.

You've tried to have a conversation about each other's feelings. She's tried to make you understand how she feels about these other girls and you've tried to make her understand that you're not interested in them. However, it sounds like you still may not fully understand each other and you both have less patience every time this subject comes up.

In a case like this, I'd agree to disagree. Accept that the way you view these interactions will not be the same, regardless of how you talk about it¹.

So if you know that you can't agree on this point, how can you continue to be in a happy trusting relationship?

Set boundaries.

Sit down together and get out a piece of paper and write down a list of boundaries. These boundaries should be created such that if you follow them all to the letter, she can trust that there's no funny business happening and you still have as much freedom as you'd like.

Maybe this list includes "No co-ed hangouts after XX:XX pm," or "Hangouts with the opposite sex must be in a public place," etc... but it can also include boundaries for her: "No shouting when upset about girls," "Nothing physical when upset," etc...

If you're out with friends and you girlfriend gets upset about a girl you're with, despite you following the boundaries, it means you've both found out that your boundaries don't correctly express what she wants. Don't panic or devolve into an argument. Give her time to cool off and then have a conversation about how to update the boundaries to prevent this from happening again.

The boundaries will never be perfect--a list of rules simply can't properly express someone's feelings. However, the boundaries will act as a foundation of trust and a promise of conversations with a clear purpose and goal in the future when she gets upset about this again.

Best of luck!

PS: You say "each confrontation we have on the matter could easily escalate into verbal and physical violence." If there is any chance of physical violence, I would strongly suggest seeking professional help as this has some of the hallmarks of an abusive relationship. However, being random internet humans, we're not in a position to judge or diagnose which is why, again, I'd suggest seeing a professional.

^{1. This may be possible if you're willing to seek professional help (ie: relationship counseling or some other form of therapy), but I'm addressing your private conversations between each other.}

her being on very low self-esteem

That's the heart of the problem. It's not that she doesn't trust you to stay with her, it's that she doesn't trust herself that she's as good as anyone else, including any other scantly-clad women. I'm pretty sure she would behave the same if her boyfriend was someone else than you.

Considering this, all your proposed solutions were doomed to fail, as none of them address the core of the issue, only the consequences of it.

She needs to get better with herself, maybe with professionnal help. Have her tell you about why she doesn't like you looking at other women (even if you're not - remember, you're not at fault here (even for watching porn, in my book)), why she thinks you'd want to dump her, etc.

The goal is to make her realise why she's feeling insecure, and work on that insecurity. Reassure her that your intentions are not to blame her, but to find a long-term solution for the both of you.
