I like this girl but she has a boyfriend.
Me and this girl have known each other for a while, but it wasn't until a couple months ago that we started talking. We were on a trip together with out school and one night on the trip I saw her walking outside by herself looking sad, so I went up to her and she was depressed and started talking to me about her boyfriend and how she doesn't think she loves him anymore, so I was just listening and giving advice, there were other things that we talked about but it was mainly about her relationship, the next day I saw her and she thanked me and I thought nothing of it. But when we get back from the trip, me and her start talking more and she comes to me for advice, but me and her got closer and closer. I had started liking her and I told her that and she said she liked me too, a couple weeks went by and we had hung out and we talked and texted everyday on the phone, she sent me hearts and kisses and told me that she liked me a lot, and I also told her that, and one day her and her boyfriend broke up, and me and her started to talk more and hang out more, then a week later I noticed that when we talk it wasn't the same, she was giving me one word answers making it seem like she didn't want to talk, then I confronted her about it and she said it was nothing, and a couple days later her and her boyfriend got back together... When I talked to her she said that she missed him a lot and that's why she got back with him. So I was really sad because I had grown to really like her a lot. When we talk it isn't the same anymore but sometimes I can still sense that in her messages she is flirting but some days its straight one word answers.
I really don't know what to do, I still like her a lot but I don't know if I should wait around of her..
Whatt should I do?
