I’m a sahm too. I totally respect and appreciate what dh brings to our family and he respects and appreciates my contribution. He has no desire to be a sahd and I don’t fancy doing his job either.
We both work all day. When we’re both in the house together we’re both responsible for it and the dc. Just as if we had both walked in from outside.
When the dc were small the house was low on the list of priorities and it showed. The dc needed attention and I needed rest and sleep and a relationship, the house was a poor fourth.
For a while I tried putting the house in 2nd place on that list and my health, MH and our marriage suffered.
I’d strongly advise that you drop standards a bit OP. If he’s happy to wear crumpled clothes why not let him? It doesn’t reflect on you (except to people living in a 1950s time warp and do you care?). Learn to live with a bit of mess - it’s really liberating. I know it feels like now is forever, but it’s not. And in a short while it will all get much easier.
If you really can’t handle the mess, he could hire a cleaner to do his half. Or you could hand him the dc when he walks in, put your earphones on so you don’t hear the moans and endless questions and just clean and tidy. Hoover while he’s watching tv.
But above all start talking about your role with respect. Take yourself seriously. You know you’re working hard and if it’s not possible to have a sparkling house in the circumstances (and it’s really not) put the blame for that squarely where it belongs.
In our house we have different roles and do different types of work. We are entitled to equal leisure and equal access to the money and financial decisions. There is absolutely no way that I would stay at home and enable his career progression without that as a bare minimum standard.
