Can my son get involved?

[Jenny8]

Sorry if this is a duplicate post, can't find my original.
My eldest son no longer wants to see ex, and he doesn't want his younger brother to go as he'sd worried (history of abuse).
I was exhausted after years of 'battles' over the kids, took a long time before his abuse of kids finally came to light and i can't go thru it again. I know i'm a coward, but this shouldn't be about gender of parents, i want my kids to be listened to, and i wonder if i am taken out of the proceedings, kids would get stronger voice?
I want to protect them also, but my eldest will be sitting his GCSE next summer, and i dont want to put any more stress than is. Any advice or help much appreciated.

Have you considered family therapy?

My ex won't get therapy, even tho it was suggested he receive professional help. I doubt he's going to change at this point.

It may help us, but so would supervised limited contact. Understanding abusive behaviour doesn't make it ok when you still have to suffer it, they need safety first. I don't know what to do to help them for the best.
