Well, sounds like theres something wrong with him. Have you tried talking to him, asking why he does it?

If you're not his gf he doesn't really owe you an explanation, those are the chances you take when you fool around, if you don't like it, don't do it.

There's nothing wrong with him. You're allowing him to use you, and that's your own problem. Stop messing around with him if you want to fix it.
