Blaming game

Everytime something around this house happens the first finger points to me even if i don't do it. This morning my mom found a hole in my bed (And i have absolutely no idea how it got there) and so her boyfriend came in here yelling at me saying I did it and that's exactly why there's a hole in the bed, Blah blah blah. I'm Everytime I stand up for myself it's always this that comes out of their mouth "Your boyfriend is brain washing you and filling your head with shit" So i want to say My boyfriend has never put a single thing in my head. He was the one who's always been there for me when I'm being put through this shit. This has been a reoccurring thing since (I'm turning 18 in a few days). He has told me when i move out "My boyfriend's family is going to kick me out because the way I act" I do not "Act out" all I try to do is stand up for myself. My mom just sides with him and Tells me I'm in the wrong so the other day i asked them to tell me What i did or said wronf., But of course they couldn't tell me and didn't say a word her bf just started screaming at me. My boyfriend's family has helped them every way possible they can. They have washed clothes for my family because we can't have a washer where we live. They have helped my mom move out of her house When they we're Running E on gas and Its about an hour drive from here to there. They have offered to do everything for her but at the end of the day she treats their family like ahit. moral of the story is They blame everything on everyone but them
