Hi @Ohhhhhlalala I’ve read your posts but not the full thread. I can imagine many people are of the opinion to give husband the heave ho!
I want to give you my perspective and why perhaps his behaviour has become so extreme. I think you are 100% right he isn’t depressed. But he is struggling and taking it out on the family, which isn’t healthy.
Myself and one Dc have asd, husband too I think but he refuses to get diagnosed. Over the lockdown period all symptoms were amplified and we are still getting over it, if you can imagine there’s like a time delay - over the confinement and change in routines we held it together. Now there’s the change back to normal, all that emotion and messed up feeling we couldn’t express is coming out.
If your husband has asd he will have been more traumatised by the covid period than joe bloggs, add to this the addition of new fatherhood/twins (which anyone would struggle with) and now another baby. It’s too much. While this in no way excuses his behaviour (autistics can be dickheads too), I think bearing in mind the enormous amount of change, stress and pressure with limited time to regulate himself, seeking help for him urgently would be preferable to throwing the towel in.
Have a look online about autism traits and list as many as you can with examples of his behaviour from childhood on. Go to the gp and have him referred, meanwhile get him assessed privately if you can (make sure in keeping with NICE guidelines/able to be ratified by the nhs for the purposes of accessing treatment later).
There are many strategies you can employ to lessen the issues in the household pretty much straight away. But a bigger help would be him being able to potentially access pip (which is a gateway to other financial support and provisions even at airports/venues - I bet he’s a barrel of laughs in the queue for bag drop) carers assessment for you etc etc
Ultimately if your husband is unsupported asd, after the last few years and with the pressures you describe he won’t be in a good place.
The diagnosis process is hard but the increase in quality of life with professional help/funding is huge (pays for therapies, transport, enrichment experiences such as days out/restbite hols, cleaner, home adaptations etc whatever is necessary)
Wishing you all the best of luck, I hope he is open to getting help.
