I think my boyfriend went to a strip club and lied?

RRSB2
I told my boyfriend of 1 1/2 years that if he ever went to a strip club I would break up with him - no hesitation. I don't set any other rules on him whatsoever, just this one. I consider strip clubs to be cheating. If he looks at a naked girl it is the same as me having a naked guy in my room. He has known this since the beginning.

Last Wednesday he mentioned that his friends were going to a strip club on friday and that he wanted to go with. I asked him if he was serious of kidding around because I was shocked that he would even think I would be okay with it. I told him what would happen if he went. FURTHERMORE, it was our anniversary on friday so I reminded him that he promised to spend time with me!

After that conversation he started acting really distant, and completely blew me off that friday, saying he had to work late and went to bed early! He also refused to spend time with me on Saturday, and now he barely even wants to talk on the phone.

Honestly, I have a really bad feeling that he went. It makes me feel horrible that he would lie to me like that, but he's known about my ONE rule for a long time.

Is his behavior a sign of a guilty conscience?
