Boyfriend's Gram died and he went to a strip club, what now?

My boyfriend of 5 years knows how I feel about strip clubs and (negatively). His cousin called him that morning and told him Gramma died. I consoled (we live together). Then he continued on his planned shopping trip that happened to take him to a strip club. I called to check how he was doing knowing he thought a lot of Gramma and he tells me he's got to step outside to hear me cause he's at the strip club. He comes home. Huge fight. Now I'm numb. Stay or go???? Not first arguement over this type of behavior.
