AITA for being mad at my "stepdad"? I (m24) have always lived with my mother. She (f53) met a man about 2 years ago (m39). I had initial problems with this, but respected him and understood she couldn't just have me in her life.

She died 2 weeks ago by a heart attack. It hit me hard, but it didn't seem to harm him as much. I spend the first week sitting inside and being depressed. She gave her will to him and me (mostly me) and the first thing he did after the "black week" was buy a shit ton of mcdonalds.

He's been spending all his time in MY house and has been drinking tons of beer and hasn't been cleaning up after. I've has to clean up after him and cook all the meals. I called him out on this and he got offended.

AITA?
