Hump 'r 'n dump 'r.. don't chase just replace my man..
Hey, stay on top of your game and spend time with her here and there but don't see her more than twice a week. She'll feel more comfortable around you and surely give up the ass.. Meanwhile, don't commit to her.. Say something like "Well, I'm a busy guy and I don't know if I have time for a true commitment right now. You're an awesome girl and I definitely want to get to know you better, let's see where we can take this." She'll melt like butter and you don't have to commit.. Just don't hit it TOO good man, else she WILL fall in love.. oh and for the love of god PLEASE pull out!!!!!
