Yes lots but I think it depends on the outcome you want and how bad it has got.
The easiest option is to split. Pressure on mum instantly drops, mum thrives or at least feel a lot less pressure than there was.
The other way is much harder because it piles the pressure on mum at a time when she really doesn't need it. It involves unpacking all dad's copying strategies both the positive ones pre children and the negative ones that have crept in post children. Dad probably won't be able to help because he won't recognise what he does or why. Then putting them back in place regardless of what you or the kids need need.
Eg he needs twenty minutes peace and quiet to transition between work and home when he gets home. Pre kids or small baby you won't notice, you'll have just got into a routine of sitting quietly for half hour. In good times he may be able to tolarate sitting quietly and watching a mutually unwinding DVD with the kids. As part of the a family unit, the kids are desperate to see dad and tell him everything the second he jumps through the door as are you, you may be desperate for a break after looking after an autistic kid all day. The social expectation is too much. You start getting avoidance tactics..... unpleasantness to everyone who comes anywhere near, going playing computer games. To fix it you need everyone including the kids to put there own needs second. Amusingly you might get a snippet of self awareness as dad's general mental state improves "why does everyone scatter the second I walk through the door." Then you start reintroductiNg low social expectation activities where the mutual gaze is at something else other than each other (tv)
So the question is can you and should you forgive the avoidance strategies, especially if these have got pretty unpleasant and possibly abusive . Can you methodically spot and fix all the same things in another adult that you can in your child, with the right degree of respect due to the fact this is an adult.
The few that survive mum takes on a hell of a lot and has a very full awareness of what she is doing. I know few that do but they do as much if not more asd-wise for their partner as they do there kids... I don't live with anyone full time, it would be too much for me
