I’m so sorry you are in this position. But there are some very wise people here and I hope they pile on to provide advice. Some may be waaay off base but 9/10 we are pretty spot on.
It might be tough to hear. But the intent is to help you get out of this nightmare with your sanity. We are savvy enough to spot the gaslighting and manipulative behavior from cheaters.
First things first. Your husband has cheated. It doesn’t matter if it was physical, emotional, or something in between, but it’s based on the fact that he has broken a vow, has not remained truthful & is lying to you. And himself.
Based on experience, your husband will continue to deny anything happened. Whether nothing happened is really not the issue. The issue is that he broke your trust.
I don’t know if you’re able to get actual proof that he did see in an escort on his business trip. He may have been dumb enough to put it on a credit card or withdraw an unusual amount of money from your bank account to pay for the services. Unfortunately, it’s going to come down to a "he said – she said" situation.
You have now learned that your husband is the sneaky calculating type. I’m sure that was shocking to you.
I don’t know where you go from here. I think it’s going to be a series of frustrating conversations, especially if he never admits the truth.
Unfortunately, most of us here will disagree that "nothing happened". He certainly took advantage of an opportunity where he was able to get away with something — except he forgot to delete the text or message.
I would not be surprised, based on typical cheater behavior, if this is not his first time doing this. His only mistake was forgetting to delete the evidence.
