Maybe you should just leave! I mean I really? Obviously nothing is getting anywhere, maybe it's time to call it quits, unless you are just in love with her. But most importantly, you have to think about yourself. I am in the same situation. I get an excuse everytime. When sex comes around it's just mutual masturbation, which does nothing for me, and he knows it. I am thinking that there is someone else and he is just afraid to admit it, and the same could be the case for you.
