Not a problem at all :)
at the time, 11 and 6. It was hard for them, but we have actually worked hard to show reasonable civility to each other and that makes a great deal of difference for the kids. I have also tried not to badmouth him (I save a lot of anger for here, which is a great deal better than letting it out in real life).
My ex-MiL, who had not wanted us to separate, said 18 months after the divorce that we were better parents apart than together. I'm grateful for her kindness and that she said it; I hated the necessity for separation and her words feel a bit like a gracious blessing.
He was extremely passive aggressive, to the point that (as ive said before here) his best friend of 36 years got in contact with me to ask if I was alright. No overt fury and rage but under the surface it was there and it was extreme. For a time he seemed to be alienating the children from me, but that seems to have passed fortunately. There were some financial shenanigans but it was worth it.
Once you decide to separate it's essential to physically separate. If you're doing it the sensible way, you plan ahead of time because as with any separation, you just don't know how the other person is going to react once faced with divorce.
But staying in the same house is no good. Honestly, you can't start healing until you do physically separate. I was exceptionally lucky in that I hung onto the house just, but it would have been worth moving into a tiny flat tbh if it was in a reasonably safe area with a decent school.
The children see him regularly. He was absolutely awful to me but it was ... ineptitude ... rather than malice most of the time, and he loves them. In some areas he's a better parent than I am - he goes out with them more, that's difficult for me. However, I regularly have try to explain his behaviour to them or simply listen when they are struggling with certain elements - his inability to listen or to compromise at all. Or to comprehend their needs, which is very sad because he would if he could. He really does love them and they know it, which matters a great deal, even if he can't really 'see' them in many ways.
If only, as @SpecialMangeTout says, there had been more understanding when he was small. If only he hadn't learned silence as the only response to conversation, once he stopped masking, and the only response to disagreements. I am not proud that I ended up shouting at him at times, because talking reasonably didn't work.
In the end, had he been able to accept his autism and to accept, even if he didn't understand it intuitively, that I had emotional needs, then we would have had a much greater chance of the relationship working. Im still sorry that it didn't. But it never had a chance.
