Is my coworker romantically interested in me?

I’ve been married for over a year now, mostly happily though hubby and I do have our moments. I recently started a new job and moved to a new area far from family and friends. Hubby works remotely and isn’t too interested in making new friends so that burden falls on me.

I met a guy at work a few weeks ago who started with me and has a similar cultural background. We hit it off pretty well and since he’s married and has a dog as well, I thought he could be a good family friend. He told me his wife is still at their old place, pretty far away, trying to get a transfer to this location and they have a 4 month old. We’ve only met twice since he doesn’t regularly work at this location but since the work chat system is common, he messages me pretty often on there to talk. Over the last few weeks, the conversations have gotten much more personal, with him asking to meet, if I’ll ever be transferred to his location and all the fun we could have, etc. Honestly, I’m not interested in sticking around on site any longer than I need to for work. He would occasionally mention his wife and the dog at first but lately he’s stopped mentioning either of them, except to insinuate to me that his wife doesn’t care about him. I suggested a while ago that when his family moves here, we should plan a play date for the dogs while the rest of us hang out. Now he’s telling me he doesn’t know when they’ll move here and it might be a long time, and he doesn’t get to see me often enough, basically indirectly saying we should meet up sooner outside of work. I commented on something he was talking about and he said those are things one should talk about after getting drunk. He also keeps calling me a dear friend and tells me he enjoys talking to me.

Maybe I’m overly sensitive but some of things he said definitely feel inappropriate coming from a coworker, especially one I haven’t known for very long. I know having a baby sometimes creates distance between spouses, and physical distance also doesn’t help. I also told him about another guy who’s from the same place as him in his native country and he completely shut me down saying he’s not interested in meeting that guy, even though that’s exactly what he was so interested in me for, and I’m not even from there, just have a similar cultural background!

I think he could be a lively friend if that’s all there is to it but I’m not interested in anything more. I’m also hesitant to tell my husband about all this, he’s not the most even tempered person and I don’t want the situation to get out of hand since it involves someone from my workplace.

Opinions pls! Both on what you think this guy is trying to do and also what I should do about it.

Thank you!
