Is my ex playing mind games? (this is long.. so only read if you have the time).?

Maybe he wants you around so you can buy alcohol for him. No but really, he's young, immature, and needs attention. It is hard for some guys to grasp the fact that his ex will be seeing someone else. I'm guessing the girl he "loved" for two months was younger than him. It's one of them "i want you more because I can't have you" type of situations. He is just causing drama. How do you feel about him? Do you still like him? If not, then drop him, change your phone number. He sounds weird, like obsessive, so be careful too.
