How do you end a 20 year relationship? I've been with my husband since I was 12. We have 3 children together. He has another child that was conceived within our 20 year relationship.

He's demanding, mentally abusive and some times physically abusive. I keep telling my self that I need to stay and be there for my children. But I am so tired.

I'm lonely, unhappy and I hardly feel anything anymore.

I don't understand why I can't just walk out.
