"I can't see myself going to a lawyer and saying "my husband is entitled and a bit of a twat". That's not grounds for divorce.
BEsides, there are 3 kids who need stability and their dad.
Yes, he's a bit of a child - but, the children see it. They comment that I do it all. And, they have already sussed that it's not ok to take someone else for granted.
So, I grudgingly accept it for now and wait for the penny to drop. He won't/can't see my point of view, but, one day, one of the kids will flag this shit up to him.
My plan is to teach the boys that if they show their partner that they cherish them by doing chores without being asked - they will get more blow jobs because they'll be irresistible.
And, the girl has a firm handle on not being beholden to anyone.
So, they'll be ok."
I can see all sorts of wrong there.
I'll start with 'so they'll be ok.' That is you telling yourself you have the situation in hand, when in fact your H has all the power here and is not afraid to shove your face in it.
Next is 'one day, one of the kids will flag this shit up to him.'
You need to be the leader here. This is not the job of any of your children. Nor is it the role of any of your children to contribute to any kind of a moral victory for you over your husband.
By the time any of them is ready to confront him on his attitude they will already feel nothing but contempt for you and one day they will show that too. 'Yes, he's a bit of a child - but, the children see it. They comment that I do it all. And, they have already sussed that it's not ok to take someone else for granted.' This is not a victory for you. This is a picture of a family of children living with a lot of anger and a lot of shame. Their comment that you do it all is not a compliment on your martyrdom. It is a plea to you to stop allowing him to walk all over you and dump the anguish of seeing that into their laps. The next step is open contempt for you for allowing it.
If you think you will teach anything to your children by mere words you are mistaken. Your children learn by your example and by your H's and by the example of how the two of you operate together. Your boys may end up doormats or they may end up entitled twats. Same goes for your DD. No matter how they end up they will be angry, and ashamed of their family.
Grounds for divorce is anything you feel it is.
There is more to bringing up children in a healthy environment than providing stability.
