What are the chances that he'll want me again?

When guys have a girl that they constantly hookup with usually they will always go back to that girl. But never for a commitment or a relationship, it will only be for the . So if you start developing true feelings for him, try to not let yourself do that, because he doesn't truely like you if he's off with other girls and just using you for a hookup. Some girls are okay with this, but others aren't and they don't like being 'the other girl'. If you do wind up falling in love with him remember, if he's leading other girls on or in a different realationship with someone, but still hooking up with you, he will always do that. And i don't think you'd want to be the one being cheated on or being led on by someone.
