My boyfriend went on a boys night out (not a bachelorette) and came home at 6 AM in the morning. When I asked where he was he said he was at the bar. I told him bars don’t stay open that late and then he told me he went to the casino. I knew he was lying so I checked this phone behind his back. I saw that he spent over 200 dollars at a strip club and a message from his friend from a few hours beforehand saying are you still at the strip club? I’m disgusted and I don’t know what to do. We have been together for 3 years living together for 1.
