What did he mean by saying this?

I’m being a girl right now overthinking a situation. And I just need a straight up answer.
There’s a guy I work with whom we tried the dating thing, but I could get a sense he wasn’t taking it as seriously as I was or at least we weren’t on the same flow of expectations. So when we talked about it and could tell he didn’t know where his head was at, I told him no worries and it’s okay if we just go back to co workers and friends. Don’t get me wrong, I didn’t want to; and there’s still a soft spot for me, but I’m also not gonna wait around you know?

but since then, I could tell he’s been distant. He’s never rude in any way, just doesn’t act as conversational or upbeat compared to other coworkers. I just feel a distance, and I’ve been trying to do things we did even before dating, like joking around with him and stuff, but I feel resistance on his part.

but one night he said something that maybe I’m overthinking due to past wounds. There was a moment where it was just me, him, and another coworker, and when the other coworker walked away and it was just us, I tried to make some small talk, and he responded with “I’m sorry, I realized you always ask how I’m doing, but I never ask you how you’re doing”

it caught me off guard, and my immediate response was “it’s okay”. Even though, yes, it not okay. That was actually one thing I noticed he never did that I struggled with…

but I can’t help but wonder.. did he say that because there’s still feelings there on his part? Or am I overthinking it?

I don't think it's feelings, maybe he just realized you try to initiate always conversations but he doesn't want to reciprocate the attention, and felt a bit guilty for that. Afterall he dumped you so he probably feels awkward about you in general.
If he had any feeling he is now doing his best to ignore it, after you decided to quit it. And this is respectful, he didn't start to cling or become petty or anything, he is trying to keep things professional. Of course he may be still attracted (not exactly "having feelings" maybe, or maybe yes) but that is just normal, it's not like he stops being attracted all of a sudden, he needs time to move on and to focus on another woman. So as long as he is not bothering you (and it seems like he is actually keeping a healthy distance) then just let him process it and get over it naturally. If he wanted to commit to you, he would have done that, or would have come back saying he realized he made a mistake or something, but he didn't because he knows he can't grant you anything stable. And he is respecting you by not playing with your feelings anymore.
Let some more time pass, when he will date another woman and you will date another guy probably you both will be able to be truly neutral again at the jobplace.
He will manage his side by himself, you don't need to investigate or anything.
