Numbering on the paper does not follow from the abstract page

My page numbers are not following a proper order. Right now what I have is the Abstract page numbered 1, but the Introduction page is also numbered 1. I want the numbers to follow from the Abstract page, that is, 1, 2, 3, and so on. The numbering starts in the Abstract and ends in the very last page of the paper going all the way through.

This is what I have on my preamble

documentclass[12pt,letterpaper]{article}
usepackage[margin=1in]{geometry}
usepackage[english]{babel}
usepackage{amsmath}
setcounter{secnumdepth}{3} %the depth of section numbering 0 means no
usepackage{pdflscape}
usepackage{afterpage}
usepackage{capt-of}
setlength{parskip}{1em}
usepackage{amssymb} 

EDIT:

My abstract is in the title page and the intro:

begin{titlepage}
title{textbf{Title }
{small textbf{    }}}


author{John Doefootnote{Department of XXX, University of XXX, City, State Postal Code, Country. E-mail: url{[email protected]}.} small{Department of XXX, University of XXX}}
date{ small {today}}

maketitle

begin{abstract}
 Blah blah
end{abstract}
noindent textit{blah:} XX; XX
noindent textit{Keywords:} X; X; X
end{titlepage}

%Need to look into Nash Bargaining with interest R costs taken into account. will change x_underline (cutoff)
%doublespacing
onehalfspacing
setcounter{page}{2} %solves the problem
section{Introduction}
label{Introduction}
