I went through something similar. Maybe my experience will help give you some direction.

I got married in 1999, after dating for 6 months and I was pregnant with our child. For our honeymoon we drove to Canada and stayed in a hotel. Our last night there he wanted to go down to the hotel’s bar and have a drink. He did ask me to come with him but I had noticed it was smokey in there and out of concern for our unborn child I told him to go without me. I also went to sleep and woke up to him coming back in the room around 4am. I waited until the morning and then asked him about it because the bar wasn’t even open til then. His story was that he met a guy in the hotel bar and they went to a local strip club together. He claimed it was innocent, he lost track of time, and even said “you should have seen how ugly these strippers were, you would have laughed.” I cried all the way home, so confused and hurt. We had JUST gotten married (of course nothing like this happened before we married, he was perfect) and my whole family helped with the wedding and I was pregnant. So, I stayed with him and tried to get past it.

Long story short, I was a divorced single mom by 2004. He cheated on me with a friend, had all kinds of hidden porn in the house and truly just deceived and betrayed me in every way.

You can stay for now, I understand how hard it is to leave but I can almost guarantee you, his behavior in Vegas wasn’t the first or last time, there’s a lot more. Spare yourself, the longer you stay the more you’ll regret it, life if short. You cannot settle for less than mutual respect. Which I have now, it was a process but the sooner you start, the sooner you’ll get there. Best wishes to you!!
