Caught him. Need help :(

My husband has been sneaking out every Saturday for about 6 months now. He says he goes to bars but I've suspected he's been going to strip clubs. Today was one of his best friends funerals a few hours after it ended he claimed to go be with their mutual friend to help greive. I knew he was lying. When he got back I smelt the smoke and alcohol so I told him I followed him to the strip club and he admitted to it. But is adamit about knowing which one I followed him to. I withheld that and tried manipulating it every way so that I didn't answer. So he shut down and is ignoring me until I answer so I went into the bedroom and I'm making him sleep on the couch. What steps should I take?
