I met a girl who I liked and she liked me, but I met her at a party and she was already with her boyfriend.
After a few days I talked with her on facebook and she said she likes me, even admited that she loves me a little. She went out with me. Our date was a succes, we felt good, but she doesn't want to cheat her boyfriend. She misses me, she clearly likes me but she doesn't know what to do. She doesn't want to make him suffer(this is what she told me), but she told me that her realtionship isn't working and she wants to be my gf but she doesn't know me too well (we only met 1-2 weeks ago)

So what do do to make her break up with him, and make her my gf?

No one knows this one?

I know she seems all perfect to you. But don't do it bro. Save your effort and heartache. Either way it wont end well.

#1- She leaves her bf to be with you. What makes u think she won't leave you for someone else.

#2-She continue being with her BF and keeping you on the chase at the same time going back home and get on to the same bed with the BF. (no point in that)

So are u really sure you wanna be with this girl? Speaking from experience

Totally true. I admit. I have a same experience.
