Let me preface it - no cheating, no affairs, nor will it be.
I have been working with a colleague in the same company for a long time. We work on projects together, so we do not work constantl together. Equally, in a hybrid environment, we are not always together in the office, which helps.
So, at times, there could be weeks we might not be in touch, and then other times, we are in touch daily. It's been all fine for a while, but he’s been confiding in me over the years and has started to call when we are wfh. Nothing sinister. The issue is that in the office, he will come over to my desk (far away from his) and chat for some time, and then he will come again and walk with me to the tube home. The next day, he won’t say hi when he sees me. The other day, he came over and said I noticed you looked down, so I came over to make you smile It’s all very flattering but confusing. I would hate to think my DH would say something like this to a work colleague!
I am just pissed off at myself as, over the years, I have started to enjoy this attention. Sometimes, I shut him down quickly and avoid him around the office, but we have to work together sometimes. I can’t work it. He’s just friendly (as some days he’s so cold), or he’s playing me. The situation is irritating me big time. I should look for a new job. Or do you think I should completely blank him? The issue is that over the years, he’s been a good person at work who has your back, and there aren’t many of us who are “normal” at our place of work.
