I had to help a very good friend of my daughter's financially after my daughter's death. She had a new boyfriend who seemed very nice and so forth, and was well employed at first. He then gradually began to control all of her movements. He began to demand to check her phone. He would follow her. He would call her several times a day to find out where she was and when she was going to be coming home.
In the case of my daughter and that phone bill I mentioned, it may seem like a minor thing, but he never let up on that phone bill with my daughter. Even until three weeks before she died, he was still bringing up that phone bill. She said she did not owe that money. There's a form of debt that is alleged to be owed that can also be held over a woman's head.
Gaslighting is another form. I was told by my ex-husband that if I left him, nobody would ever love me enough to want to marry me again, for example.
These things are all intended to keep you under their thumb, so they know where you are all the time. You get isolated from your friends and family, partly because you're embarrassed. Then it becomes a question of how to leave, which, as we all know, is a very dangerous time. I'm so proud of my daughter for having had the courage to leave.
