hi im going thru a painful break up. me and my ex had "broken up" a few years ago, but we kept seeing each other and even living toghether in the same house to support each other, she has a 7 yr old kid, nice kid. and me and the kid got too attached. the thing here is that my ex met someone, and i met some one too. and my ex doesnt like me being with someone else. also, she doesnt have any family or friends. only her kid. and she recently had problems with this guy she just met. sooo. she begs me no t to leave her.and i even had sex with her out of pity.. and i feel soo bad for it. any advice?
