Abuse chances the way you think. It can be fixed. I’ve seen it happen. But you will have to take action, abusers tend to never change.
If you cannot do that, if you keep believing you can’t then you have given up. This is my last reply about this. I wish you the best and hope to hear from you in the future when you are in a better situation.
On the other hand, I am just a stranger on the Internet, so I have no real info about your situation. But I’ve seen hopeless situations like yours before, and I’ve seen them get resolved. So I hope you find a way. Because there always is.
