Is it normal i don't think this is normal [domestic abuse].
I just woke up to my mother (53 yo) screaming violently. This kind of thing used to happen very frequently for almost no reason. Laying in bed I ignored it until I heard my step-father crying like a baby (75 yo), and when I began to listen in, she was screaming "STOP CRYING" repeatedly. She was also insulting him horribly. What disturbed me is that she's screaming at him to stop crying after I know she made him cry by saying and doing some erratic things. That's the only time he cries, when she is having a meltdown that he can't control understand or control.
Suddenly, I heard my step-dad run into the bathroom and slam the door shut. She was banging on the door violently. I think he got scared and opened it. I got up really quick, and found him on the bathroom floor crying with her standing over him screaming at him to stop. I obviously ripped her out of the bathroom so he can get up.
What should I do? This is my brother's apartment and not theirs. I love my step-dad, and call him my grandfather, but he and my mother(who is the reason we didn't want them here) basically showed up on day. They were evicted and said they would go to a homeless shelter the next night. They never did. Yesterday, I resolved to move out after my grandfather told me that my childhood experiences with my mother did not happen, but were drawn "from books" and "imagination". I couldn't believe he would say that to me, yet low and behold: here we are again, except that I am not a child anymore and he seems to be the weakest link.
This whole thing today started because apparently she was on the phone with "the government", who claimed they had not lived at their previous apartment. My grandfather piped in and said that he will fax them a lease.
I don't know what to do. I think that I should get her forcibly evaluated. I don't know how though. While my step-dad is crying, she was hovering over him telling him to stop screaming. He defends her, which is sad. He makes her food. He listens and agrees with her non stop babble-fest. He takes orders from her, following her every instruction. She's not mentally stable, she never has been.
I can't tell you how many times (in the past) we've had the cops called on us because of her screaming. Shit is different now, this is not her house and she does not pay rent. She doesn't contribute anything.
