Did she do it or no?

My wife knows about my cuckolding fantasies and we used to play story games about her old interests( she never did anything with them)
There is one gentleman she calls sometimes when she requires help in her work.
I noticed her paying special attention to him like arranging softdrinks for him,getting irritated if some staff refuses work he tells them etc.
Few months back I met him outside her office had casual chat as I know him.
When I went to her and told her that I met him.She was startled and asked " you met him?" I was casual and told her yes I did.She asked what did you talk about? I told her it was about new car he has bought.But I was surprised as she never asks such things when I meet other acquaintances.
Few days back when I was ***** she told me " he came 3 times" her tone was not joking and we were not having sex.
I asked who? She named him.I asked her deatails and except place and time she described the positions,what he was wearing,what positions and which part of bed in hotel they did it.She was detailed to extent telling me " he had small hair on his balls"
" He booked room"Positions they slept after each encounter.when I asked her why wouldn't he tell anyone about it she said" because he is married too much into his wife" " no questions asked while checking in"
When she saw me upset,she changed her narrative and told me she is very good at making up stories and nothing really happened.
It excites me very much and I told her you should have told me before doing it.she said it was "instantaneous decision".
I need help from experienced guys did it happen or not?
Kindly help
