What should I do? (read details)
I went on a beach trip with a bunch of my buddies, some girls, and some other guys. I got to know one of the girls really well and we went to the beach together and we did almost everything together. The day after we got back she wanted to ask each other the same question so we said it at the same time and were dating now. But a couple of weeks ago I went somewhere and met another girl at a pool and I ended up cheating on my original gf. my second gf broke up with me a week ago and they never found out about each other and now my second gf (now my ex) starts flirting with me and telling me she loves me and that I was the best bf she had ever had.And my gf just got back from Brazil and she said she got me something and I can't help but feel guilty about it. What should I do?
