You deserve so much better.
My ex-H was like this. I got so used to it that I rarely noticed how much I did alone, and didn’t really realise what was normal in a relationship.
I had a suspected pulmonary embolism when pregnant. We already had a 14 month DD.
When I was asked to go to the hospital for a CT scan and to wait for results, I needed childcare for DD. He suggested I take her to the hospital with me and arranged for his DM to come and sit with her just while I was in the actual scan. (He also palmed as much as possible on to his DM, and still does, despite her age!). I ended up being there for 7 hours in all. With DD in a buggy, with me walking her up and down the corridors to try and get her to sleep. The results were positive and it was a stressful day.
The weird bit was though that I didn’t even ask him to come as I had just got used to him saying he couldn’t take time off work (self employed, could easily take it really)
Things started to click a bit when I took DD for an operation when she was 2. I actually
asked him to come, even though I normally did things alone, as I was worried. He said he couldn’t. She had a bad reaction to the anaesthetic and I ended up sitting crying on the ward and being comforted by a random patient 
There were many incidents like this, both big and small, he had opted out of family life completely.
Later, after I’d left him, I was at work when I heard a male colleague talking to his wife on the phone. He sounded really concerned and I heard him saying “No, I’m coming with you, I’m booking the day off work”. It turned out she had a cyst on her ovary and he was insisting on being with her for a scan. It wasn’t life threatening but he WANTED to be with her. I thought he was the best husband ever! Now I know that it is normal to support your partner.
I am happily married now and have a DH who actually takes time off to be there for us as a family, even though the DC are not his own. He even shares time off work for DC sickness and holidays! (Ex DH obviously doesn’t do this as he “has to work”)
Ex still treats me like the hired help, but I don’t have to put up with it anymore.
A favourite recently was when he messaged me to tell me he has booked DS in for football training on a weeknight (my contact time as he only does every other weekend) at 4.45. I work full time, and don’t get home until after 5pm.
When I reminded him of this he asked if I can finish early. No. Then if my DH could do it (also running a business full time) and then eventually asked his 73 yr old DM to pick up and do it.
Because... “I can’t finish early” 😂 (still self employed)
So OP, the reason is I am sidetracking into my own story is to try and show you that you can do it and will be happy again. Maybe even meet someone else one day if you want to. A normal loving partner who wants to support you.
But, be prepared for your DH to get worse if you divorce him. I didn’t realise my ex was emotionally abusive and controlling until after I left - I thought he was just a selfish workaholic, but there was a lot more under it that I couldn’t see at the time (probably because I was so bloody busy and exhausted!
