The problem was not someone cutting off the other, it was how it was handled afterwards.
I have absolutely zero interest in getting back in contact with my other brother who sexually molested me, our younger brother and several other boys. When I finally confronted him some years ago, he talked on and on about how much pain that had caused him. I pointed out there wasn’t an apology in his explanation so he added that he was sorry “terrible things had happened to you.” I told him to fuck off and never come by my mother’s house while I was visiting.
Nor my younger brother who told me that I killed my son (who died as a baby) and a zillion other things. Like Annie-Xmas’s younger sister, somehow I’m at fault for everything bad that’s happened to him. He refused to get treatment for his bipolar condition, so you can imagine how much trouble he can find.
He’s homeless and lives off my mother’s money and soup kitchens.
I tried for years to help him. At one point I offered to pay him if he would do volunteer work. If he could only do one minutes, I’d pay him for one minute. He refused because I owed him the money.
We would go through cycles of emails. First, he’s start off nice and ask for advice, just to sucker me in. I’ve always wanted to help him, so I’d respond. Then he’s start making demands. I’d nicely let him know I couldn’t do it. He’d try emotional blackmail, threatening to kill himself being one of his favorites.
Then when that wouldn’t work, he’d attack me. This is when he’d do thing like say that I killed my son, etc.
I would block his email account, only for him to start another and continue trying to contact me. Eventually, I simply changed my email address and never looked back.
He’s the type of guy that if he were to go craz(ier) and start shooting people, it wouldn’t surprise anyone.
I’ve had to limit contact with my mother. She’s revered as a saint by her nephews and nieces, people at her church and at her former work, but no one saw that’s she’d turn into a rag doll at home and expect me to take care of her. She’s still a battered wife, even though my father had been dead for 30 years.
I had to give up taking care of her. She would suck all my energy and turn around and say things were all my fault. Little things. She blew off my kids’ birthdays (they were born two years and three days apart). We called her on Skype so she could say happy birthday. Apparently the next day she sent an email asking for our new address so she could send a present. I didn’t check my mail that day, so the next morning I got an email tell me that I could hate her all that I wanted, but why was I cutting off contact with her grandchildren and how much heartache that was causing her. All because I didn’t respond within 24 hours of an email. It’s been a lifetime of emotional manipulation.
For the OP, cut ties if you need to. Don’t take advice from people who haven’t ever been manipulated nor abused by someone.
