Tell your Husband, to hire you a babysitter or Nanny.
Even for just a couple of times a week.
Really.
He can't expect you to be a hermit Mom.
You are Human.
I have a friend, with 3 kids, and her Husband has to travel ALL the time for work, he is hardly home, and has long hours.
So, he got her a part-time Nanny... to give her a break. So she can even do errands, without going bonkers.
She'd have days, when she'd just CRY, because she was just, like a Single Parent. And her Husband, was hardly home, so when he was home, it was just like a hotel stay.
The thing is, since a Husband is HARDLY home due to work, then HE ALSO NEEDS TO PROBLEM SOLVE THAT, and be a participating Spouse, too, and help the Wife, even if he is hardly home. Being he is hardly home, he will NOT know, they everyday toil, that a Mom/Wife does.
And for YOU, you NEED to TELL YOUR HUSBAND, so that, he knows darn well... what it is like being like a Single Mom while he is away.
My friend's Husband, luckily... understood his Wife, and so he got her a part-time Nanny. Who comes in the evening because that is when it was hardest, for her. She has 3 kids, ALL young and boys, and super super active.
