You knew what she did before you started dating her so why are you even bringing this up now... . Sorry, but guys and girls like you make me wanna puke. Don't stick your dick in (or open your legs up )if your brain is going to cause you trouble later when he/she falls in love with you... You're being an asshole for being with her even once if your basic instinct is to recoil from what she's done in her past, never mind staying with her until she's emotionally hooked on you too. Bleck! Shame on you.
“The willingness to accept responsibility for one’s own life is the source from which self-respect springs.” ~Joan Didion
