This... has had to have gone on... for awhile?
Not only now.
It is his... gripes and his personality tendency.
Regardless, it is really maladjustment.
And really, negative upon you and the kids.... and him.
He needs, to see a Doctor. To rule out depression or any other mental malady.
He... will not be satisfied with anything.
Nothing, satisfies him.
And, his deep seated hang-up... about your time with your sons.... is really abnormal.
He doesn't want you to spend time with them, but yet, he doesn't want to spend time with them either. Once he does have to babysit.
The thing is: you said he would love for you to work 12+ hours a day... and NEVER see your sons.
... THIS, is really, abnormal.
And he gets 'jealous' about any time you spend with them.
THIS is abnormal.
You are not dealing with normal irritations here.
Your Husband... needs mental health Therapy.
It could be depression, or it may not be.
How as HE raised, himself??? Any siblings?
I'd say, he's pretty toxic.
He is really a Negative-Nelly, to say the very very least.
I would, pack my bag and take a vacation with my sons.
