To answer your question more broadly (in a way that might be helpful to other people who could come across this some day), abusive people try to make you dependent on them.
They want to isolate you from your friends, family and support structure, so that you won’t have anywhere else to go. This can be accomplished by creating fights between you and these people, spreading lies, using religion as a weapon, or just making it difficult for you to ever see or interact with them (e.g. no we can’t go to your brother’s wedding).
They try to control you physically by monitoring your mechanisms for communication like your cell phone, the internet, or limiting your ability to drive so you can’t travel to see other people. It’s common for abused women to not be allowed to renew their driver’s licenses for example. This is often done through a climate of suspicion (“you’re cheating on me”) where the controlling behavior is explained by false suspicion. Be on the lookout for guys trying to set up patterns of controlling what you do , how you dress, and what you say (e.g. “you look like a whore wearing that”, or “don’t ever talk to me while I’m watching football”) especially guys who are quick to be suspicious or jealous. These are big red flags. In a healthy relationship, your partner will encourage you to be who you are and support your personal growth, not try to inhibit that.
They will try to destroy your self esteem (“Nobody else will ever love you”, “you’re fat”, “you’re stupid” etc.). Then they build your self-esteem around themselves.
As @bookish1 mentioned beware of Gaslighting. Where the abuser trains you over time not to trust your own memory.
Then there is the cycle of abuse where they abuse, and then apologize, you reconcile, and then they reoffend. This repeats. You feel trapped because you have no one else to turn to, you’ve been alienated from your friends and family, you can’t easily talk to anyone about how to get help, they are in complete control of your life, and for some perverse reason you love them, hoping that things will get better.
As suggested in the other thread, it might be a good idea to volunteer at an abused women’s shelter. You could help out some women who are in a very difficult spot in their lives, and build up a lot of self-worth, not to mention how good it feels to help those in need. You also might hear some of their stories and might pick up on some of the similarities between the victims and yourself in terms of the way they respond to abuse. It might go a long way towards helping the healing process.
