I never asked him about his personal life it's actually him who's always asking me personal questions like where I've studied, where I live, who's in my family, my likes, dislikes etc.
He was the one who initiated everything with me but I wasn't responsive to his advances like the touching, flirting, spending extra time with me, changing his schedule just to see me etc.
2 weeks ago, one of his old friends at the office asked him how the marriage was going, I was standing a little far behind him when this happened and saw his face in utter shock and he was totally tensed and kept looking back at me apparently to check if I had heard his friend.
I couldn't make out the whole conversation but from what little I heard he said that "you should only marry the right girl and it's been 3 years let's what happens".
Yesterday, while we were talking about work related stuff, he mentioned that he has a wife, I didn't react to it nor did I say anything. I don't think it's any of my business to do so but I do feel bad about why he kept doing all that he did for so many months.
It's just that I don't know what to say or how to react since we're in a professional setting. I can't yell or shout or have an outburst.
After telling me about the wife, he continued to stay back after work to hang out with me. I didn't speak to him during this whole time as he was just quietly hanging about.
