Search Results: making girlfriend jealous

I know I know this is a question where I should really choose who the best person is, but even there I would really like to hear more people on this matter, because the more people the better the choices I can make.

1) She was my ex for some time, we dated for about 3 months though, then she dumped me and told me that I was too desperate for her. However she has been chasing me for a long time now, maybe 3 months or so, she seems very keen to be my girlfriend as she doesn't give up and is always there for me and doing stuff for me trying to call my attention (cooks for me, comes to my house, gives me rides)...since women RARELY do any of that, big points for her. Yesterday we almost had sex too, so the feeling is mutual.

2) I met her when she was a freshman in college, she is the best looking all of three, who seems very nice too. However there is a problem, I think she was playing hard to get and making me jealous which I didn't like and I stopped talking to her. She tried to call my attention in her subtle ways so I can go back and talk to her again, wheb we had class, which I like. Unfortunately our college is huge and we don't have classes anymore, I don't have her contact information either and the only way I can talk to her is if I "run up to her". I have the biggest sexual tension with this girl, more than the other two.

3) She is very attractive too, we work together and I think she likes me as well, as she is very nice to me all the time. We chat a little sometimes at work, when we can and I really like it. I haven't ask her out yet, although I should have. The only problem though is that she is graduating this year like me and she will move away withich I will too, which will suck because I don't like long distance relationships.

Any how which one would you choose if you were me?
