So my wife (33f) went to a conference... Im a (42m)

Ok so just a little context first I have been married to my wife now for 3 years, my previous relationship ended from infidelity after decades of marrage more on this later.

So the current situation and what im really hoping to get a perspective other then mine is....

My wife was invited to go to a typical corporate conference, put up in a nice hotel, everything paid for etc . So she went out to a dinner with her coworkers abd bosses, this was a very fancy dinner so she was dressed to impress makeup and hair done, shes a very beautiful and attractive woman naturally and rarely ever puts on makeup and hair etc. So when we video chatted that evening after dinner, we chatted about the day and she also had quite a lot to drink and was "tipsy" I told her she looked really beautiful tonight, later she said i wish i knew what it was that made you say that? ( I also regularly tell her this so its not out of the ordinary) i said idk what it is maybe your hair? And this set her off she said that she just doesnt have the motivation to put in the time and effort into looking like this and that she just wishes i would prefer her natural and that im conditioned by society. I was like just take the complement, you know i think you are beautiful natural. She continues to tell me how much more attention she gets from the opposite sex when she puts in effort with her hair and makeup and again about it being a weird social standard that she will never understand so i replied then dont put in the effort, it honestly makes no difference to me if thats how she feels, she then said but then i get exta attention from you, anyway she repeated again that i am sooo conditioned by society and it makes her feel inadequate. This is all from a complement..... At this point i feel like shes just baiting me into an argument so i said this "I dont understand why you feel its ok to get all dolled up for your work and workmates but when it comes to your husband its superficial and conforming to society" seems like a double standard? Keep in mind i have never asked her to be something she doesnt feel absolutely comfortable with and that alot of people feel confident dressed up looking their best men included. Long story short the convo pretty much stopped here a little before 11pm a little after 11:30 i text her and askes her if she was sleeping, i get a text back no i came down to the bar for a drink heading back to my room now. So she calls me and says i have to tell you what happend, (im sorry im trying to keep this short so im going to cut out details), she procedes to tell me that when she was at the bar she started chatting up a guy, she knew his name too, had a good convo, finishes her drink and says goodnight im going back to my room, gets in the elevator and he followes her and gets on the elevator too, at some point she gave him her room number.... He then proceededs to call her to see if she wants to hang out. At this point shuts it down and says im married and you have a fiance and this is inappropriate amd hangs up.

I get really upset at this, because i can not see any reason why she would as a married woman be doing this, what reason would you give a guy you just met at the bar your room number? She said that she is naive and assumed that since they were both in relationships it was ok ... i say this is bs, please help me see things differently. Then she turns everything around on me saying that she has never been more unseen or unheard and my brain is playing tricks on me.

Anyway what are your thoughts? Oh the reason my previous marrage ended, wife hooked up with many different men on business trips like this which i discovered through videos of the events.

Thanks for reading.....
