He is the bad one here, not you.
Do you love this man any more?
re your comment:-
"I am tired of this, I want to keep the marriage going for the children and all other aspects are fine",
If you are tired of this, then let the marriage end. Why should you pick up a financially massive bill for him down the line?.
Do not drag it out for the next x number of years or even worse till the kids go off to university (which is around 15 years away). You will truly be emotionally ground down by his financial and other types of abuse of you by then and you will feel too old to leave. They will certainly know by then that the two of you are living a lie.
Keeping the marriage going for the sake of the children is never ever a good idea. Its a terrible burden to place on a child, for them to have the knowledge that you and dad only stayed together because of them. What do you want, their thanks for doing that?. They will not thank you and even worse could well accuse you of putting him before them in their childhoods. There are no prizes for martyring yourself so.
You and your H between you will simply teach them that a loveless and controlling marriage is their norm too; they will not say thanks mum to you for doing that to them. You stay because its habit and its somehow "easier" and the unknown is too scary for you to currently contemplate. What you are experiencing here is really death by 1000 cuts.
As for the all other aspects are fine, I would say otherwise. Financially abusive men are often abusive towards their chosen victims (the plural is deliberate) in other ways as well, often such men are verbally abusive too. Your children pick up on your overall unhappiness and perhaps even worse blame their own selves. Its no life for them or for you for that matter. You and your children deserve better.
After all the only acceptable level of abuse within a relationship is NONE. That's right, NONE.
