Instead of imagining that he's a player, try imagining that he's having thoughts just like you. "She seems nice, but it's long distance and I'm really not ready for a longterm relationship. I think I'll just go and have some fun, because I'm lonely."
Don't expect him to want you more than you want him. Imagine that he's a lonely human.
