Is he actually interested in me or just playing around?

Is he interested in me or just enjoying the attention/friendship? I’d really appreciate honest outside opinions!

I’m confused about a guy I’ve been close with. We knew each other before he became my coworker, and now we’re good friends and coworkers. He always touches me a lot like touching my belly, ruffling my hair etc.. also sends cute messages after i helped him like. “you’re my lifesaver 🫶” or “you’re too sweet.” I think he likes physical touch to people but everyone says he touches you a lot.

But he’s never asked me out or defined the relationship. His actions feel romantic, but he never makes it official.

Is he actually interested in me or just playing around?
