Most Helpful Guy
First of all, no that not cheating. Its sitting in a workplace cafeteria by yourself and then your co-workers sits down at the table...now you're alone with him...is that a date? No. Is that cheating? No. But what is more interesting to me is why you're so nervous about this whole thing. Don't get me wrong, I'm not accusing you of anything, but it kind of seems that you might have some type of interest in this co-worker. I think that because you're very concerned with such a simple and innocent act...or is it?
Telling your partner about that encounter is not needed or useful. He might wonder why you're making a point to tell him about something so trivial. If you were on a public bus and a guy sat down and started talking to you about nothing in particular would you feel the need to let him know? Perhaps if the tables were turned you'd like him to tell you. If that's the case what you're doing is passing your insecurities on to your partner...and that's not fair.
Remember cheating starts in the mind of the innocent...that's you. So if you don't have any interest in your co-worker having a bite to eat together is an act that happens in every workplace, and I'm pretty sure people don't run home and tell there partners out of fear of cheating.
Bottom line is this, I don't know you obviously, but you sound guilty of something very innocent, so then maybe its not so innocent after all.
I hope this helps!
