OP, I bet if your parents
knew just how bad your spouse physically abused you, they would be singing a much different tune about your divorcing him. I understand that it's really tough to disclose to others just how bad things are. Been there, done that.
I know divorce is not pretty. In fact, it can be downright
dirty. Sure, the children may develop behavior and emotional issues from it. Yes, you may be alone for a l-o-n-g time as you focus on your children for many years. And I agree, co~parenting can be tough, esp. when doing it under acrimonious circumstances.
But try to look at the bigger picture here OP for a minute.
Your husband is physically abusing you. It really doesn't matter if it is due to a health issue. That is not relevant since that would be his issue,
not yours.
No one should have to live like you are living. In fear.
By staying w/this man, you are overall doing more harm than good for your children. For them to grow up in a violent home, to see their Father treat their Mother in such a manner would scar them emotionally way more than a divorce would.
Plus, their model of what a marriage is supposed to look like will be screwed up.
I would be singing a different tune if your husband actually was actively seeking therapy for his anger issues and making a genuine attempt to work on his problems.
But after
three weeks he still hasn't done anything!! That just shows me your marriage and the children is not at the top of his priority list right now. Also, his words carry no weight as well.
OP, I know you have thought long and hard about this, but as a victim of domestic abuse/violence, you have no other option but to divorce this person.
Under no circumstances should you stay married to someone who physically abuses you in any way, shape or form no matter what disease (?) they may have.
You need to break free from this violent chain for your two small children.
Financially I think you will be okay.
Also, I would talk to someone about your husband's violent tendencies so he could only get supervised visitation w/the children since you feel their welfare could be in jeopardy.
I wish you all well. Keep your head up.
