I (18m) have always had a tough relationship with my friend (19m). we fought a lot, broke apart and about a month ago I apologized to him. We made up recently, and when he ran away from his home (abuse) my mother called me saying she couldn't tell him no when she called him. that's the setup. He showed his gratitude in small ways, helping me pick parts for a computer and letting me serve myself in the heaps of snacks he bought himself (which I rarely did).

That was short lived, though. After a bit, he went from a happy surprise to a thorn on my side. He moved his computer in, taking my desk in hostage, stays up and keeps me up when we both have school, and does close to nothing in the house. He can't take as simple as a request as "dude keep it down" when its late at night without telling me to fuck off.

Recently, both my mom and him crossed a line. He wanted to see his brother and my mother invited both of them in. Without telling me a thing before ten minutes ETA. I was furious, so mad that I pulled the confession that it was the idea from my mom. The brother never came, but I was still fuming.

(added part) I still remember when his girlfriend was on visit and my girlfriend caught them, with him at his computer and her under the desk. *My* desk.

Am I going nuts here?
