Don't let yourself become a booty call. While I can see why he's torn about getting into a new relationship, he has to realize that you're a new chapter, if not a whole new book!
That said, if he doesn't want a relationship, then he shouldn't be allowed to receive the "perks" of a relationship (ie. kissing, sex, etc). Otherwise, you will be a call girl, so to speak. Tell him that you understand how he feels, but that you're looking out for yourself too and can't continue a physical, romantic relationship.
It also wouldn't hurt to reassure him that you wouldn't hurt him like his ex did (even though you can't tell the future) ... Sometimes, dudes just like to hear that.
no autographs, please!
