Thanks for your kind words. I didn't feel brave at the time, I often had to take it one step at a time. Looking back I'm proud of myself for surviving him.
When I was being given the silent treatment and disengagement, I felt very, very hurt. I tried to talk to him about it but he would erupt in rage, deny things and blame me and my unreasonableness.
A good therapist helped. I had someone to talk it through with who was a voice of sanity in all this emotional chaos. I recognise not everyone could afford that, for lots of my life I couldn't.
Once I recognised my husband was being abusive, and cheating, Gas-lighting, lying, getting you to doubt your own thoughts, withdrawing, is abusive, I trained myself to detach.
Again it was a step at a time, but the more I observed his behaviour the better I could cope. It still hurt like hell and I had nightmares about this time for several years.
But it released me from reacting to his manipulations.
So, MN, a therapist and slowly detaching from his carry on. He'd detached from the marriage a year or more before I was able to. There were some good online sites too, but I can't remember them now.
Chump Lady was good.
