Casual, FWB or Something More (getting confused lately)

So I’ve been seeing this guy for about 3 months now. We met on Grindr and from the beginning I was looking for a hookup, no expectations. But over time, things got a bit more blurred.

We’ve hooked up more than 10 times. Shifted from fuck and cuddle to stay over (until now that I’ll stay over every time). There’s once I invited him to shower together and now he will just walk in and we’ll shower together (is that normal?)

Also, he’s given me hickeys (something that happened recently twice in a row—is that a thing or I’m thinking too much), but we’ve never had a real conversation about what this is.

He’s gone quiet for a while and then suddenly reappear (probably because I didn’t cum—he mentioned that but didn’t tell if this is the reason).

This is my first time having this kind of situation, normally I’d just fuck and go. Thus, I don’t know what’s normal or what’s me catching feelings. Sometimes I feel okay about it. Other times, I feel a bit emotionally “empty” afterward, like I want more connection or clarity, but I don’t know how to ask without scaring him off.

The last time we met was Saturday night, I stayed over, and we had a nice time. He even made a comment before I leave like “you didn’t get a chance to practice your massage” (a callback to something I said earlier). It felt like a soft hint that he might want to see me again (or perhaps I overthink).

How do you tell the difference between soft emotional comfort vs actual romantic interest in this kind of dynamic. I’m not trying to lock him into a relationship, but I just want to understand if this is going somewhere. I just don’t know how to feel.
