Do abusive men ever change?

[WhyAmIHavingDoubts]

I'm scared and worried at the same time putting on a brave face.

I'm worried to post details so can anyone tell me if someone who's been physically abusive can ever change?

I'm having serious doubts.

A typical abuser tactic is to try to convince their chosen subject they've changed - because by losing them they've lost control of them. They haven't changed. They are using their skills in a different way. Once they have you back under control the behaviour will return. Your doubt is good. You got out, don't allow them to reel you back in

The declarations aren't real. He will revert back to type after the honeymoon period should you rekindle. It isn't safe to stay with an abusive partner. On average 2 women a week are killed through Domestic Abuse and I too was almost part of that statistic because I kept returning.
Even a 4 year prison sentence didn't change him, Victim Liaison informed me he'd refused all courses and still blamed me entirely.
So to go off my experience alone, no, they really don't change they just get better at it. Scumbags they are and they all follow the same pathetic script.
Give Why Does He Do That a read and it'll help answer those doubts you have.
