is he self centred/ uninterested rather than interested in me ?

Hey guys, https://www.reddit.com/r/dating/s/rUaG79V0M6

You can see a previous post of mine which sort of explains my situation.

Potentially have a thing going with someone from work, he’s great. We get on really well, we text and call outside of work but I’m unsure where I stand with him. Over the last few weeks developments have been made and it’s implied he’s into me. But I’m struggling understanding his interest/ if he’s actually interested. Perhaps mixed messages?

I’m the type of woman who is naturally someone who asks questions, when I meet new people or see old friends, I’m always asking for updates on life and actively trying to get to know someone. This is the same for this guy, I’m trying to get to know him.

When I sat back and reflected on it, I don’t think he is. Whilst we spend so much time chatting, I don’t feel like he’s making too much effort to get to know me and my life and my interests. Maybe it’s because we work together ? As I said in my previous post (linked here) I’m new to dating, I’m a late bloomer dater, I’m trying to figure out what boundaries are happening / what to expect. I just always thought that when someone would finally be interested in me, they’d made it very known in their actions and I’m trying to get to know me and who I am as an individual and follow up on things I’ve said.

I ask him many questions but it doesn’t seem as reciprocated.

Before the comments come for me, this is a general discussion point, I’m not making any decisions or anything. It was simply an observation. As I said I’m new to dating so this all feels scary / unexpected.

I’m just curious as to if anyone else has experienced this? Maybe he just isn’t someone who gives a lot away. I’m almost just stuck where I’m at/ in my head about if it as it’s all so new for me. Are some people just less of an open book? Even for romantic partners? Should I be concerned at his lack of questions? Can any men advise on this? Are some people just more reserved.

I’m also conscious we mostly interact in person in a work environment, which I know sways things.
