I'm so tired of him and his inability to simply even consider the option that indeed things can be reshuffled somehow as to give us all balance. He's obsessed and simply not willing to accept (even though he knows it to be the case) that this life is not sustainable
I’d suggest that he doesn’t want to reshuffle things. Because he enjoys what he’s doing more than he enjoys spending time with you and his child.
He’s not unable, he’s unwilling.
I’m sorry to be so blunt. But if he wasn’t happy he would change it.
I’m telling you this now so you don’t spend more time ( years ? ) trying to help him and persuade him that things could be different. I know he says it’s not a choice but it very definitely is.
I know this because I used to be married to him ( not literally obv ) .
And yes it is sustainable for him. If / when you leave him, he will replace you very quickly, because he needs staff at home. So be prepared for this. He will find another woman and tell her his sob story of how his ex didn’t love and support him, she was selfish and demanding. He will wine and dine her ( surprisingly finding the time away from work ) and she will fall into his arms, promising to be everything that you are not.
Remember that he’s only pretending that his life is hard - he LOVES it. It’s like running marathons - they all collapse on the finishing line, say never again and then refuse to wait a couple of weeks ( as advised ) to start training for the next one.
My ex is still working like that in his 60s. The only people it’s not sustainable for are you and baby. Your husband is A OK.
And he will almost certainly be very mean about money if you leave him.
See how he has 100 creative ways of avoiding spending time with you and his baby? And 100 excuses for why work is important and you are not ? Soon he will have 100 reasons for why you are not getting any of his hard earned cash and 100 creative ways of avoiding child support.
This is very easy in the UK if you are self employed or own your own business but I don’t know about the law where you are.
Remember that the work and the money are what give him life meaning. He’s not going to let you take either of them away from him.
So plan your leaving very carefully, I’d start saving money somewhere safe now if you can.
I’d also get legal advice sooner rather than later. Don’t leave it a year. Remember you can get the advice but not tell anyone or act on it.
