My wife received an ambiguous message from a gay man, deleted it and lied to me that she was a lesbian, sometimes carrying it behind her back.

Imagine: If you always send ambiguous messages to a girl, what is your psychology? Of course, I want to do something bad. It's strange that there are no ghosts!

So, now put yourself in someone else's shoes. Do you think that guy who always sends ambiguous messages to your wife will still be a good person? Obviously not!

More importantly: your wife may adopt a tacit attitude, which is troublesome! That man will have a chance!

Therefore, it is recommended that:

Immediately expose his wife's lies and ask them if there is anything else.

If not, tell her to cut off contact with that man and forget about it.

If there is, then she is heartless, and you don't have to preach. You can directly find out the evidence and show it to the people in their unit, so as to embarrass them. And you are married, you have the right to ask them for compensation for mental damage!
