Looking for some honest male perspectives on a situation that’s been really messing with my head all insights welcome?

I've worked with this guy for years. We’ve always gotten on well — there’s been natural chemistry, a bit of flirty banter, and a closeness that gradually deepened. Over time, we started messaging more often outside of work. It moved from casual chats to more personal and sometimes suggestive messages, and eventually things got physical not full-on sex, but definitely intimate.

The thing is… he’s in a relationship.

What’s confusing is that he sends really mixed signals. He’ll encourage me to date other guys, but then he asks for details like who the guy was, what happened, even whether anything physical happened. It feels like he’s trying to stay emotionally involved or keep tabs on me, even while acting like he’s not that invested.

He also really tunes in to how I’m feeling. There have been times when he’s noticed I was off or upset, and he’d offer to give me a massage or bring me a chocolate bar because I wasn’t eating lunch. He’s worried I wasn’t eating enough. It’s little things like that caring gestures and attention that make me feel seen but then I wonder: is it just part of the game?

He definitely picks up on the fact that I have feelings for him. I’m not someone who gets physically close to someone lightly, and I think he knows that. So my question is this:

Would a guy knowingly keep a physical and emotional connection going with a girl he knows has feelings for him, even while in a relationship just for ego, comfort, or sex? Or could it be more complicated, like confusion or emotional attachment on his side too?

I guess I’m trying to figure out: am I being used, or is there something deeper he’s not admitting? I’d genuinely appreciate any honest feedback, especially from guys who’ve been in or seen situations like this.
