Name change for this one. So I'm laid awake contemplating this, and really need some guidance-
A colleague has been flirting hard with me for 6 months (including him sending some pretty graphic dick pics). He'd even asked me to meet him. So glad I didn't as I found out last night in front of all my colleagues that he actually has a girlfriend, and it seems I'm the only one who didn't know.
I feel totally humiliated, especially the way he let me find out, and if I'm honest, I really liked him and I'm quite upset. I called him out on it- sent him a message to give him the chance to explain himself, or even apologise, and he didn't even bother to respond.
So here's my dilemma- in a few weeks we have a big work conference, and I'm the organiser of an evening dinner for a large group of us at the end of the first day. He is included. Should I send him an email to politely suggest it would be better if he didn't attend? Or just refund his payment and say nothing? Or just allow him to come and have a nice time, despite the fact he didn't even think I was worth an apology? Or should I drop him in it by telling our colleagues that he's not the nice, awkward, shy guy they all think he is, and is in actual fact a lying, predatory piece of work???
I should add that he is my (female) current team manager's best friend.... makes it even more of a tricky situation but similarly I'm pretty sure she'd not be impressed by his behaviour.
Any help here would be so appreciated.
