Would you want to know?

[HotelNotel]

In need of some advice here.
Recently started seeing a man, he spent months messaging me beforehand. However I have since found out he has a long term girlfriend, and I'm pretty sure they're also trying for a baby.
I am devastated as I thought he was lovely, now I realise what he's really like and that he was just using me.
Obviously I no longer want anything to do with him, however, I feel guilty that there's a woman out there falling for the same nice guy act, who's invested years in a relationship with this man. My question is, what would you do, would you tell her? Would you want to know if you were her? I can't stand the thought that men will continue getting away with this sort of behaviour unless we call them out on it.

I've tried looking at some similar threads for support but the answers seem so mixed, so any help or wisdom would be appreciated.

Is he in a position of seniority to you? Do you work in an industry where verbal recommendations are key? If you feel he has the power to tank your career, then protect yourself.

@EvenMoreFuriousVexation yes he is. But luckily any moves or promotions would be done through fair competition. My concern was if he gets really malicious he could lie or destroy my reputation. I felt like I protected myself by letting my line manager though, but still I'm conscious I'd be viewed as a trouble-maker if I did tell his girlfriend.

100 times yes i would want to bloody know!!!!

I think you have to tell her especially as they are TTC!!

i would email her to ask to meet her, that way, yes she would know it’s you but also you can show her proof without giving it to her, and you could maybe explain your side better.

please also be aware that she may already know what he is like (you would be surprised!!!!) and she may not want to know. Just from some experience!

I’d want to know
