Strip clubs?

My ex boyfriend and I are working on us and he's trying to gain my trust back and the other night he went to a strip club with his friends and I'm livid. He's telling me I'm over reacting and he's not even slightly interested in making moves on a stripper BUT when we broke up he slept with one so that's just a lie. I haven't spoke to him in like two days am I over reacting? What's your thoughts on your SO going to a strip club?
