Oh love, on not criticising you at all, I hope you don't feel I am. Just with the autism, it's potentially he has and therefore can't necessarily change in the same way a common or garden abusers can.
My ex was/is abusive. He has no issues or excuses other than he wants to rule and contol. I hate him. Our son doesn't like him either. We're delighted he's gone and will never ever darken our door again.
Trust me, I didn't say my friend thought she was the problem, but You know how it is, we feel if we just did this, or that, it wouldnkeepthe peace. What I say about her now is that she knows it wasn't her, nothing she could have done would have made a difference and the blessing is that she knows it's not even his choice.
It is comforting somehow. Knowing that there is a real reason for it rather than him just being an abusive monster.
Sadly in my case it's not relevant, I wish it was somehow cos the relief it gives to know there's a cause must be immense. Friend actually gets on better with him when she sees him than she has done their entire life together. He is still insfuriating, reorganising her entire kitchen one day for example when he was vision to see his daughter.
I think however her situation may not be entirely relevant to you.
The course I take is mine, he likes it/doesn't like it, not my problem. I don't allow him to pass judgement, I don't allow him to control or intimidate me any more. I am me.
Not the terrified, agoraphobic me he wore me down to. I'm The kicking arse and taking names me I always was. Just older. I literally don't give a toss what he thinks, I don't ask his opinion or permission on anything. He hates that, but he's abroad, has been for 5+ years and never did any of the heavily lifting. So screw him.
We just have to do what works for us. I sincerely hope that you can find a method that suits you. At least he's abroad too. Less interference and less poisonous behaviour with the dc.
