<human>: So a few months ago I met a girl on a dating site. She was closeby, cute, and brimming with personality. First date landed a kiss and good first impression, she just came over to my place for a few hours. Next evening she comes over for a movie. We discuss briefly about how neither of us are looking for anything too serious, and she tells me she's seeing at least one other guy. We agree to an open deal, we have some great sex after cuddling up to a movie. Next day we have some more sex (lot of consecutive times ;)) and hang out. She's into a lot of the same stuff as me, has a nerdy appeal to her, and she's smoking hot.

 I seriously start to develop feelings but cant really tell her... yet. Fast forward a week later, I take her to an outing to meet some of my friends, and we all come back to my place after for some drinks etc. We had sex again, for the last time =/ Over the next week I have her over just to hang out and meet some more of my crew. Things seem to be going great she's clicking well with everyone. The next week or so I try to make plans, some fall through. Finally she tells me she was looking for love, and loves her ex, and they're getting back together. She insists we should still hang out just as friends, because she genuinely enjoys her time with me according to her. I move on, tell her we cant be friends and distance myself. Today I find out shes single again. Whats the move??

Summarize the given text in a few sentences.
<bot>: Hook up with a smoking hot and intelligent 18yr old girl couple months ago. She gets back with ex after a few weeks, and is now single again.
