A girl from my group of friends had some problems with her boyfriend. They were having fights all the times and stuff like that. I started to talk to much to this girl and we were having convos via Fb about how a good relationship should be and stuff and she liked the way i think. We were getting really close through those convos.When we were going out for coffee with our friends she was always sitting next to me. Then one day i told her (via fb sadly) that i like her. And she told me that she also likes me.And she also told me that she liked me from the first time she saw me (6months ago).Something i forgot to mention is that their relationship is 8yrs old and they had some small break ups and a big one that lasted 6 months and she got into a new relationship after 1-2 months of their break up but she started missing him again so she broke up with her new bf and went back to him.So as i was saying she told me she liked me and she also told me its the first time this happens to her.To get to close to a guy and have feelings while she is in a relationship.She broke up with him then coz she wanted some time for herself to see if she is gonna miss him or smthing like that.While she was single we were getting even more close to each other, we were having big hugs , kisses on her neck(she also did that to me), holding her hand some times. She didnt want to give me a real kiss tho until she would understand what she wants.Although one time she touched my lips with her lips and another time a gave her a quick kiss on her lips :P.Also she was telling me that she wanna kiss me badly and that she couldnt controll herself from not doing it.We had some kinky texts on fb like telling me she wanna make love with me and stuff..she also told me she has started to compare me with him.One day she told me that she had to do sex for like 1month coz she doesnt feel like it anymore with him.Anyway she went on a vacation with her friend so she can be alone without anyone to think clearly and when she was alone there she started missing him.So 2-3 days after, she came back from holidays and they are again together.I dunno what to do, i know my mistakes..i chased too much and also the situation was hard alone coz she had 8yrs relationship.Even tho she liked me so much as she told me she went back to him.They still have fights and it looks like she is not really in love with him..its like their relationship is toxic.What im doing is trying to move on but a part of myself still wants to try more..maybe when she will break up again!? but with less chasing to make her attached to me.Also what to do i meet her many times in the week coz we have the same group of friends.3days now im not going out with them coz i dont wanna see her so often.
