I met this girl online, we've been talking on the phone and everything seems great... we start talking about our hangouts and after some more conversation I find out she goes to one of my buddys favorite bars. Turns out they went out once and slept together.. she says she was drunk and regrets it, but I cant get over the fact that she's slept with a close friend of mine... she does not understand it, but I tried to explain to her how close I am with my friends.. it would be like her dating a guy that slept with her sister. She really wants to meet up.. I guess she's pretty into me even though we've never met and I explained to her that we may not even click in person and that I wanted to remain friends, but I cant see myself seriously dating her. She got me to agree to two dates, if I still can't get past it, then we're just going to be friends. Am I out of line for not wanting to date her?
