Coworkers to…?

My coworker (28/m) and I(35/F) have a really great vibe and connection. We’ve been working together for about 6 months and have really created a strong foundation. We smoke pot after every shift to shake the day off. in the beginning it was like 10-15 minutes but now we are spending upwards of 30-45 minutes after every shift talking and smoking. We dreamscape a lot and talk about all sorts of things. We sometimes finish each others sentences, but stop ourselves from saying it all the way through out of fear I guess. We’ve recently been spending time together outdoors, going to rivers and whatnot, even took mushrooms together once. It’s been really fantastic getting to know him. We don’t really talk about how close we are, we’ve just become close. He makes inside jokes in front of people with me about our mushroom trip(we didn’t tell people) and even included me in with “us” owning a bar one day together. We work side by side most days, he even admitted to me twice yesterday he prefers to bartend with me over others. We made more plans to go to the river again soon as well. I guess I’m just a bit confused. We clearly are vibing really hard, but are totally stuck in limbo of what is happening and are we just friends or do we like each other more. I don’t want to ruin the connection by pressing, but I can’t get him out of my head. The most we’ve said to each other about hanging out has been ‘you are my kind of weird, we clearly vibe and we like being around each other. It for sure feels like a slow burn situation, but I don’t want the flame to go out because we are both stupid.

I guess I just don’t know what to do or how to approach it. Help
