It gets better. I broke off with my entire family except for wife and kids a few years back, I now know it was a good decision and one I should have made possibly forty years back. I kept hoping that there would be a normal relationship someday and I forgive myself for hoping that would happen because that is what we see all around us, everyone loves their kids on TV and at work and we love our own kids. Why wouldn't you expect that from your own parents?
My wife had to make the same choice and it wasn't easy for her either but was more or less made for her when her mother attacked our daughter right in front of us. It wasn't discipline or verbal abuse, it was hands on throat fighting over a dispute in a game of croquet!
It does get better.
Part of going no contact with a parent is their disregard for it and continuing contact. In my case I made sure that every time they called I made a contact for the number they used and never answered that number again. My wife had to threaten a court order. All of the renewed contacts made it hard all over again.
But it does get easier. And it is, by definition, better than the hopelessness of repeating the same behaviors and hoping for a new outcome.
