<human>: So I'd been seeing a girl that I'd met while on holidays during the summer, initially not much happened but she offered to meet up again, and since then we'd been on 7 or 8 dates, been to a few parties with each other, and we had been making plans to meet each others' parents for the first time (distance was a bit of an issue).

A few nights ago I was out with my friends from college celebrating one of their birthdays, she was out separately with her college friends. Out of the blue she shows up in the club that I was in (there was no indication of this happening before), where she tells me she had gotten with the guy she was seeing before me that night again. This guy had chosen another girl over her before and left her miserable. She also told me that even though she'd tried really hard to like me that she just didn't.

Am I right to feel aggrieved that it took her until after getting with that guy, and whatever alcohol she had consumed that night to tell me that she had just been leading me on all along? I can deal with the fact that she doesn't share the same feelings for me, but I find it hard to understand why that guy gets rewarded so easily given his decision before, and I was simply an afterthought.

It's the second time this year I've been left for someone else, it took a month or so the first time to regain my confidence, but it's a lot harder to see light at the end of the tunnel this time and I don't know how I'm going to trust the next person who comes along. Any advice or comments at all would be appreciated.

Can you succinctly summarize the text in 1-3 sentences?
<bot>: Dating girl for 2 months, seemed to be progressing towards a relationship, got with guy she'd been seeing previously out of the blue
