My aunts boyfriend is a weirdo.

So I was out at my sisters house while I was gone my Aunts boyfriend dog went in my lil trash can and ripped up my trash. And it was everywhere. They did not tell me while i was at my sisters house. When I got back my trash can was emptied. My Aunts boyfriend went in my room and cleaned it up. 2 months ago my Aunt is telling me that her boyfriend wants to kick me out. He got drunk and said bad things about me and said that he saw a condom on the floor that day his dog ripped up my trash. Every time they get in a argument he says that I’m nasty and other awful things and threatens to kick me out. I never talk to him. I lived with them for 5 months and I barely speak to him. He also has never said anything to my face. I don’t understand how him seeing a condom will get him this upset.
