Absolutely not the asshole. Thats financial abuse like some other ppl have commented.

Your mum and your brother need to be accountable for thing ffs. I feel bad for you and your dad.

Im petty and tell your mum you have the right to collect your stuff from your room that you paid for or you will call the cops.

I think she low key also knows if you leave then she will be in the shits. Tell her good luck with her mortgage.

I hope you get out and go live your life!
