Bachelor Party Guy Trip Suspicions!

A few weeks ago, my husband went on an all guys trip for their last single friend's bachelor party. The trip was only 2 nights but it was to a big party area. 4 guys and nothing but drinking...

When he got back, I could tell he was being nicer than he usually is but he was also fumbling over what he was saying when I asked him what went on. he said none of the guys did anything. He said he didn't even talk to a single girl.

However, one of his friends and I have been very close as friends and he told me more went on. I confronted my husband on it and he immediately said John was bullsh*tting and lying cos he wants me. I don't know what to believe.

I think he cheated and I'm giving him the cold shoulder while I find out more details from others. He keeps denying it but I find him secretly texting and talking to people he said is work related. He's lying!!

Should I be pissed???
