love/sex

Okay so me & this guy were seeing each other & broke up about three months ago. Everything was fine until it ended. Well we had stopped talking and then the last couple days we kind of reconnected as friends. The only problem is he made it very clear that he doesnt want a girlfriend. I would do anything to get him back but he just doesnt want a girlfriend. So tonight we were talking about just being fuck buddies i guess because why not? Well we agreed not to be fucking other people. So someone explain to me why he cant be with me if he cant fuck anyone else while we sleeping together? And somebody answer if you think we will ever have a chance of getting back together. I already know my feelings will get caught up but im actin a hard ass just to be able to see him.
