Replying to Girl trouble..

io was just thinking, there should be a sepreate forum for this, becuase i see atleast two fo these a week on here...anyway..

so one of my guy friends is going out with a girl who is also one of my friends. we will call the girl "jen" and the guy "bob". so latley when i have seen bob and jen together jen hasnt seemed to thrilled to be with him, kinda of looking around and staring off in to the distance when hes talking to her. before bob and jen started going out i knew that jen had a thing for me but i didnt think much of it. and about a week ago in my 6th hour, which they are both in with me, we had to do this partner project and you could pick who ever you wanted. well jen picked me right away and this pissed of bob because he thought they would have been each others partners. well she starts telling me all of these secrets about him and stuff and i really dont want to know but i listen anyways. and sicne then she has really been flurting with me, like laughing at stupid things and shit like that. well today she broke up with him becuase she said that she wanted a "break" and he said either you still go out with me or we r done, so there done. now im pretty sure that shes going to start asking me out which i really dont want. bob will get pissed and jen is more of a friend and i have my eye on some one else........soooo, wat do i do. i dont really want to tell jen that i just want to be friends becuase she is hurt easily and if she starts making a scene i might give in. opinions?
