My ex and I were together for 4 years.he decided we needed a break in April of this year. Through out the 4 years I did some hurtful things I never cheated never ever. But he claims I broke his heart. Its been 6 months since the break up and he has a new girlfriend. I live with his family so we have been having sex. We were each others first loves he says he wants to see some changes in me. But what I'm wondering is if he's happy with her why does he still have sex with me? He even gives me oral and then kisses this girl. He had no real girlfriends before me so I know this wasn't something he's done before. Is it that he's scared that I will hurt him again? Does he even care for her?I've decided to stop having sex with him if he chose her he's gone do right by her or at least not do the wrong with me. But there's some things I need answered.
