davening

Question

I was just wondering what there is to do if my husband refuses to daven. He doesnt go to minyan, and he wont even daven at home. When he goes to shul on shabbos all he does is talks and goes to the kiddush club. I stopped bugging him because it caused us to fight alot, but now I'm begining to lose respect for him. He wasn't like this when we got married. I'm out of ideas.
