Op please listen to the voices who are literally all in agreement here. He is a bad man, at the very least, a dreadful, dreadful husband.
I went back to work when my first child was 14 weeks old, and it was hard. I was tired to death, and emotionally destroyed. My then partner let me off the rent I paid to live in his home for 3 months, and that was basically his financial support. It didn't get any better, he was abusive in other ways, they always, always are, and I left.
This time around, my husband is a different ballgame entirely. We planned for me to take 9 months, but in the event I couldn't face it and I left my job. We live in a house we bought together, and he pays all the bills and then we split what's left. He got a better paying job for this to be possible, and I had a lot of equity in my previous property, so it is fair, but if it wasn't, it wouldn't matter.
And it's 2019. A parking ticket and a credit card for a self employed person hardly makes you feckless. His constant suggestion that you're some sort of child who can't be trusted with his money is extremely abusive.
What leapt at me is to tell you that this time round, I'm 42, and while I'm chilled, and happier, it's bloody well harder. Having a baby now is such a joy but I'd be lying if I said being older has no effect. Working at 32 with a breastfed newborn was tough, a decade later and I'd be on my knees.
Being a single parent is hard, there's no denying it, but I promise you it's still easier than living as he expects, and he will have to pay. If I were you I'd pack a bag, now, this afternoon, and go to family. Email him and tell him his lack of care, financial commitment or fairness has ruined a hard won pregnancy, and unless you split the house, get 6 months leave and share his income, you're done. That isn't unreasonable, it's absolutely normal.
