SO private dance update

My SO just told me he has paid for a private dance at a strip club while we were together. I don’t agree with him going to strip clubs to begin with and he hasn’t in almost a year. But the fact he paid a woman to dance on him while we were together makes me sick. Opinions? I can’t even look at him right now.

Update: I told him I consider this cheating and I’m very upset (in nicer words) and he told me “it’s bullshit because it’s not cheating and he doesn’t care.” I’m about to take a long walk and not come home 😡😡😡😡 am I over reacting?
