You can't convince him of anything, what you should do is contact an attorney. First visit is usually free; find out your rights.

I stayed in a bad marriage for 13 years before I realized I could get the police to kick him out as we are separated. And the house is in my name.

You cannot force him to leave, only a judge can do so.
Get an attorney and file for divorce.

repairlady: My ex filed and both Lawyers kicked him out. He is a black belt in karate and once made a special trip to a public place where my daughter and I were and he shoved me. If your husband is verbally and/or physically abusive and/or drinking/drugging, etc., you can get him thrown out before you see the Judge. See a Lawyer. Oh yeah, my ex started drinking a lot before he left. I took photos of the empty liquor bottles and the karate trophies and gave them to my Lawyer.
