Yes, this is my point. You assert the importance of protectiong teh health of you, your family, and the home it takes attention OFF of him and ONTO what he's doing...

He will respect you for protecting his home.

Example :

You are hurting me, our children, and the stability of this house hold... You need to leave.

You are a hurtful person, mean, cruel, and selfish... you need to leave

The first one is a lot more respectable of an approach...

You don't need his agreement for the first one... You just say it and exit the convo... the second one is weak and invites a lot of debate
