As I said, I can't make any decisions for you--none of us can.
If you could voice it, what would you like to see happen in your marriage?
Given your own experiences with your husband, do you think that achieving that outcome is possible?
If achieving that outcome is not possible, is that acceptable to you--to your children?
If it's not acceptable, what options can you consider?
I don't need to know the answers to these questions, but they might, perhaps, be worth considering.
