Back story (kind of long):
I used to work with a couple at a previous company. The guy ended up getting let go for "inappropriate internet conduct" (re: sexting on the work computer) with two female coworkers -- neither of which were his significant other. The couple broke up as a result of this and later got back together.
I now work at a different company with the guy. The girlfriend does not work here. It is a known fact among everyone in the department that he is fooling around with several girls we work with.
The couple announced their engagement last spring and everyone thought for sure he would cool it down and start being faithful to her. Not a chance - he had lunch with a different woman almost every day and would openly admit to some that there is something going on with each of them.
His fiancé and I are friends on social media (I will say I am more inclined to call her my friend than him, although I have always avoided hanging out with her outside of work because I find it awkward that I know he is cheating on her). During their engagement, she would post almost daily updates of the wedding planning process and how excited she was. This was very sad to me, but I didn't feel it was my place to say anything to her and just hoped that he would get his act together after they were married.
Well, they are now married and he is still all over the place. He even flirted with me a few weeks ago - I asked him how the wedding went and he used that as an "in" to start instant messaging me several times a week on the work computer about non-work related things and even went so far as to call my cell phone one night, which I think is super inappropriate and odd (before you ask, he only has my number because I gave him a ride to work before, at his fiancés request).
I'm always quick to shut him down and bean dip out of whatever conversation he tries to start, but he still has his other women.
I don't think I will ever take any sort of action to let his now-wife know about this because it's just too messy and made even more complicated by the fact that I work with the guy.
But just out of curiosity...would you want to know?
Do you know anybody going through the same thing?
