My coworker asked me if I was married, could this mean anything? Not sure if I’m overthinking the entire thing?

We were talking about work stuff and while I was opening a spreadsheet we started chitchatting. He first asked me if I lived alone, I said I was back to my parents house because I’m waiting for my house to get finished, then he said he stalked my Instagram and asked me if I was married (I have a pic of the day I got engaged saying we got engaged). I didn’t ask if he had a girlfriend because I already knew, but then, after asking when the marriage would be, he told me he had a girlfriend too, that he is “one step below”.
So my question is: could this mean he’s interested? I’ve been thinking about it since we talked, but I don't know if I’m overthinking.
