I've known this girl for a three months. I knew from conversation that she had a boyfriend so I never tried anything with her even though I was attracted to her almost instantly. We became really good friends, but I know she's having trouble in her relationship, and wants to break up with her boyfriend of five years, but they live together and are in the same tight social circle, and it seems like she's waiting until they both graduate later this year. I've met her boyfriend, and he's a really nice guy, and she only ever has positive things to say about him.
Turns out she slept with a mutual friend, most likely while high on drugs/alcohol. We've been having feelings for eachtother recently but I'm not sure if I should take it any further because it seems retarded to start anything with someone you know for sure cheated in the past.
She's 26. I've heard through the grapevine that he was her first boyfriend but this is not confirmed. They moved in with eachtother after two years and have lived together for three. Normally it would be a no-brainer, but she has such an amazing personality, I've never met anyone like her in all my 23 years. She's so much fun to be around, and comes off as such a genuine, nice, down to earth girl. I would never have figured she would be a cheater. I know for sure she's interested in me because she told a mutual friend with a big mouth, but it seems like a bad idea to get involved with someone like that. I went though a major break up last year and spent a good deal of it crying myself to sleep, I couldn't how much worse being cheated on would be.
What would you advise? Thanks for any advice!
