Am i wrong?

My husband. And I are out right now at a bar and he went into the restroom and took along time. I knew what he was doing but didn’t say anything. But later I asked him what took him so long he said he was with poepel doing coke. We never get to go out, should I be mad? I used to do before but stopped for good. Should he be able to enjoy his night ?

Edit: we are not addicts at all. Neither is he. He only does it ever when we go out for the night. I don’t do it as we have a daughter now. So I stopped but all he does is work and be home. He never goes out
