I was in a relationship a few years back with an alcoholic with anger issues. She would always want to fight me and cops were called a good amount of times. The boiling point was that she was shaming her daughter and I stepped up because she was drunk and I told her I had enough of her shit. She got mad an proceeded to take glass cups I had and shot them at my feet and ended up cutting my ankle. She then punched me in the face with rings all on her fingers and I got mad and shoved the bitch hard that she fell. She left my house, broke into my car, and smeared cans of wet cat food all the inside of my car. Even tucked them into the vents. It sucked cleaning that car on a hot summer day. The moral of the story is, love ain't worth the bullshit.
If I were him, he could force her to get anger management. He's not going to harm her and she knows that so that allows her to act the way she does. And in that respect, she is going to see him as a pussy and potentially go as far as to cheat on him eventually. Not saying it would happen. But women like that like a man who stands up to them. I know this from experience. Because when I dumped the drunkie I was dating because I stood up to her and her shit, she kept wanting me back. I said no. Religion be damned sometimes, right?
At least he is not like one of my friends who's situation sucks right now. He proposed to his ex last April and then set a date for the wedding to happen in October of last year. 2 weeks before the wedding calls the damn thing off. I ask him why, he says because they couldn't get along. She needs constant adulation and praise even on the most simplest of things and he isn't like that. So, they broke up yet in the same house they live in because they are both on the lease, she brought another dude in a week after their original wedding date and he fucked her. My friend called me pissed because he could hear the moaning. I told him well get a girl and fuck her. He couldn't because he loved her. This is still going on. Although my friend eventually found someone else, he still has feelings.
