If they're just yelling at each other, I'd say, talk to your neighbor next time the dude isn't around and see if she is alright or wants you to call the cops next time things heat up.
Yeah, some people are locked into gnarly relationships, where it seems like both people are abusing each other. Shit sucks.
man, i haven't seen her in months. it almost makes me think she is somewhat homelocked. and i'm basically on don't talk to me terms with the guy due to another thing, actually there's potential for violence if we meet next time. i basically said to him he should stay the fuck away from me. dude stood in front of the house taunting me to come out and fight him. i gotta deal with this without ringing at their place somehow. i thought of maybe putting up an awareness flyer about domestic violence in the hallway could signal support? at the same time, i don't want to be dragged into their shit. i know they've been living together for years, they lived in a different apartment together for years prior to moving into our house.
they are so loud you can hear the guy scream shit like "you damn cunt, do x/y or it's fucking on!" from outside. next time i see the dude living under them i want to ask him if he hears that shit, too.
i was oblivious to the fights cuz of my sleeping schedule at the time but then my roommate told me about it and after i had to be up when he is up i heard it, too. i don't want to call the cops on them for nothing if she is somewhat complicit due to them being used to their super toxic relationship. since i haven't seen her in ages, i can't tell if she has visible signs of abuse, and even then, some scumbags beat their women tactically, not in the face so no one sees it immediately, and this dude is putting up a friendly facade so hard while being an obvious tyrant at home that i would guess he'd operate like that.
