As long as it is "with the boys" and he comes home to me afterwards, I don't have a problem with it. If it was everyday and lunch too, I would dump him.
My sister has a problem with this. Funny story. Her husband went out with the boys one night after getting home from his deployment. They had moved to Sacramento. He knows how my sister feels so he checks in a couple of times. At one point he told her not to worry, the club they were at didn't even sell drinks, so nothing was going to get out of hand. My sister hung up, and said to her friend thoughtfully, "In Dallas, the only clubs that don't serve alcohol are the All Nudes". Her friend says "It is the same in California". SO BUSTED!!! I don't think she talked to him for a week.
