<human>: Awhile ago my girlfriend started hanging out with one of my good friends and I didn't think much of it at the time until it started being almost every other day. Them hanging out for about two weeks every other day was really starting to bother me so I told her about my feelings and she confesses that she had kissed him, cuddled him, held his hand, and he spent the night there twice. This was right before prom and I felt heartbroken. I still ended up going to prom with her and had a good time for the most part and she seemed like she regretted what she had done and wanted to move past that. I try and tell her it would take me time to accept everything she had done but I was willing at the time, but her response was that she wasn't sure if she was ready to get back together with me mentally/emotionally because she liked my (who I thought was one of my best friends from elementary) friend. 

I kept trying for about a month and she hung out with him (kissing and doing whatever she did with him), and she hung out with me (trying to explain to her that I really loved her and shedding some tears from time to time). Like I said, this went on for about a month and I was about to give up because I was tired of all the drama and tired of feeling sad for the last 30 days, but she then comes to me and says she loves me as well wants to get back together. I told her to wait because I'm not sure what to think. I may be young, but I think know what love is and I know I had it with that girl. But I feel like if I would get back with her she could easily screw me over again and I would get really scared if she started hanging around some of her guy friends. We've been through tough situations before but I feel like this one takes the cake easily. I wouldn't have done this to her but she and one of my (ex) best friends could just stab me in the back. I don't know what to do.

Can you condense the text into three sentences or less?
