Would really appreciate advice.
DH and I married for 8 years, together 11. I'm 37. No kids. He's 41 and very different to me, manual/practical job, quiet, not very sociable. But a nice and funny man. I'm in a professional job and work long hours.
The other man is from work. The first moment I saw him (when I didn't know he was my colleague) I thought he was the most beautiful man I've seen in real life. We eventually became friends. I realised a few months ago I was attracted to him. I am not going to have an affair. I don't want to leave my DH. I made an excuse to move to another floor of my building and reduced contact, but we have ended up on the same team on a project. I can't get out of it, and I can't leave my (very good) job in my (extremely niche) area. I have stopped going out after work even though I now have very little social life because he's usually there (and I thought it would look weirder if I only go when he doesn't, idk)
I have no idea how other man feels about me. He's extremely caring. He remembers little things I say (eg that my mum as she hurt her hip a week ago) and will ask me about it. He buys me (and others) small but thoughtful gifts (for example, we both like tennis, the other day he randomly bought me a pack of fun tennis ball post its), brings coffee to meetings for everyone. My DH unfortunately compared unfavourably in this regard as he forgets everything I tell him, takes minimal interest in my interests, doesn't "do" gifts.
Other man is in his early 30s if that's relevant. I was very down at work recently due to a client dying and he offered me a hug which I really did want (from anyone tbh but especially him) but I declined. It's getting hard though so aside from leaving work, which I can't do, and him leaving, which is unlikely, I need to learn how to cope and forget him while seeing him every bloody day! Any tips greatly appreciated.
