Okay, so my friend met this girl at his work, and started f**king her. This friend of mine is kinda just a player and has no real feelings toward her at all as far as I know. Hes been talking to other girls also and 2 of them i had had sex with in the past, and I didn't really care but now I met the girl from his work and i hung out with her a couple times without him. I now seem to really like her, but he kinda gets jealous when we hang out. I don't want to be a bad friend but at the same time can not change the way I feel so what am I supposed to do? Should I just stay friends with her or should I try to be more, I don't know what the next step is because I figure if I try to make a move she could b mad, but at the same time if I become really good friends with her she would just see me as that and nothing more. If anybody has any good advice I'd like to hear it.
