So about 6 months ago i joined a band with a kid who was engaged to a gorgeous girl named sydney. after hanging out with them almost everyday i got really close to sydney but never tried to let anything happen. one day i found out that they were taking a break but i still never tried to do anything with her, even though i could tell she liked me and i knew i like her. one night we walked to the park from their house and she told me she like me, she told me she has constant dreams of me, and thought of me all the time. i told her i like her too and we kissed. after that night we started kissing in secret, we would wait fro her ex fiance to go to bed and make out to a movie, or meet up at the park in the middle of the night. eventually we ended up having sex a few times while she was still living with her fiance. she kept saying she wanted to be with me and that she couldnt wait to move out so i can be at her house all the time. the whole time doing this i felt a little uneasy for doing this with the ex of a bandmate. he was a really jealous and possessive dude, and he and the band were the only problem for us to be together. so she moves out and im going over there all the time, its great, were doing whatever we want but it still has to be in sectret because she doesnt want her ex to find out. so one night after her ex being a huge dick to her i quit the band and pretty much mine and his friendship. now we have a chance to be together but she says she just wants to be friends for now. she gets jealous of what her ex is doing with other girls, and she gets mad at me if i talk to another girl. so i'm really confused as to what to think about this and what to do. i really love this girl and absolutely don't want to be just friends. what should i do!? please help!
