I want to make this one guy who annoys me leave me alone without sounding like a dick. After two weeks of "knowing" him, the second or third time I leave his house after going over (reluctantly) he asks if he's one of my closest friends and then asks for a hug. I take a different route to my first and last classes so that I don't end up having to talk to him. He'll start the millionth conversation about Rickenbackers, tell me about some girl he met yesterday and is all infatuated with, and/or invite me over to his house. He doesn't invite in a yes or no fashion, either. It's more of a "hey, come to my house after school."
He's just aggressively friendly. He seems to not recognize some things, too. He seems to not notice that I've never invited him over or initiated conversation with him, and that I respond to 80% of his invites with a probably not or a no, and I never suggest another time. I can't just tell him I don't like him and don't wish to talk to him because he's blabbed out his life story to me (just like he does onto facebook -_-) and I'd feel like a dick for just telling him I don't like him when he's had issues.
Please help.
