Dang, that’s so rough. It sucks seeing ur mom going through that. My dad used to be kinda like that with my mom too, and it’s like this constant cycle they get stuck in, ya know? Honestly, it might help just to be there for her and remind her she’s worth more than how he’s treating her. Maybe suggest counseling? It sounds kinda cliche, but couples therapy might help him see what he’s doing. I mean, he probs doesn’t even know the damage he’s causing. But yeah, man, I get u—it’s hard to watch without knowing what to do.
