<human>: So here's the deal, back in high school I dated this girl for 2 years and we went through a lot together(her mom having cancer and me having 2 major surgeries). We were head over heels for each other and had a very mature relationship.  We broke up when we graduated due to frustration with each other. We started to hang out again our first year of college which turned into her saying she didn't want a relationship then dating some other guy and me moving 19 hours away. Since then she's dated a couple people and now has had a serious boyfriend for 2 years.  We recently started communicating again and our talks got real serious real quick. We talked about past things that happened between us and basically cleared the air. Well last night we had a 5 hour conversation about us and our future and she told me she thinks her BF may propose again soon.. Last time he proposed she said she wasn't ready. She thinks it will happen in the next couple weeks and out right said to me that she wishes she could see me one more time before it happens. I want to marry this girl and would hate my self for missing the chance to win her back. Should I take a last minute flight and visit her this weekend or would it be a wasted effort?

Can you condense the text into three sentences or less?
<bot>: High school sweetheart and I are rekindling a relationship but her current BF may be about to propose. Should I fly down and visit her?
