I was married to a non-medicated BP for 10 years and I can only say that this condition will tear up and destroy a family. That's one reason I never had kids.....I didn't want to raise another generation of abusers. When kids are around that behavior, they learn it. They learn that it's ok to treat people bad, talk to them with no respect, treat them with no respect, and generally be abusive. They also learn that they don't deserve better. They end up with abusive spouses because that's what their non-BP parent did, or they end up as abusers because that's what they learned from their BP parent. I don't think it's a good environment to subject children to, and if you really want them to grow up emotionally healthy you will get them and yourself out of that situation.
I know that's not what you want to hear. You want a solution, I wish I could wave a magic wand, unfortunately I know first hand that you cant. Please protect your children.
