I'm a long term lurker who was on the original threads but got bored with the 'invaders' and their lectures, and so I retreated.
I've been married a very long time and have young adult dc, three with a diagnosis and one considering pursuing it. For a long time I couldn't see that my gentle, thoughtful children with ASD could have anything in common with their explosive difficult dad, but I've come to realise that it's all part and parcel, and about how he learned to cope with his feelings and experiences as an undiagnosed autistic person.
I mentally and emotionally detached from H a few years ago, and we (although he doesn't seem to realise it) now live like housemates. I now just nurture my family, friends and pets relationships instead. I'm always fascinated though, when I see couples having a nice chat. That would just never happen here.
Mentally detaching has done me the power of good. I recognise the shouting and invalidating and the sheer wall of noise that some of you describe, the relentlessness of it. I still get that horrible sinking feeling when he starts roaring. Yesterday he found an Easter egg on a chair and I said, oh it's for the grandchildren's egg hunt. He shouted for five minutes about my disrespect, my 'tone', the way I speak to him, my 'backchat' and stormed off upstairs for an hour. There was no argument beforehand, no snappiness or atmosphere. Its just like having a hormonal fifteen year old son as a husband. He's unable to check himself or rein himself in. I have to mask all day long but he can just be himself...
It's actually destroyed any hope of making a success of us as a couple, but again, he doesn't realise and quite enjoys the lack of demands (as he sees it). I'm not leaving - I love my house and the garden, and it's my children's home, even the ones don't live here.
Anyway, I just wanted to send solidarity to you all, and say that I recognise your lives, as I'm living it too x
