Welcome, foggy. His disease is in control of you, not just of him.
You wrote "Not sure how much more of this I can take."
How much more should your children have to take?
You can either let him bully and devastate every person in that family, ruining your children's childhood and your mental and physical health.....
or you can have the courage to get that counselor you are considering, and make a plan of action to put an END to his tyranny.
You can do this. But you need support because alone against addiction, we succumb. The addict is just too powerful.
I'm happy you found this site. Life can turn in a new direction for you today.
Take care. Be safe. Protect your children.
