Guys advice please.... F buddy situation

Hey guys please help me understand from a guys point of view .... (and gals feel free to comment too)

So I have a F buddy / FWB - best sex of my life but we live pretty far so we don’t get to catch up often (occasionally 2-3 weeks)

When we’re together we are just on fire 🔥 and it’s not just sex we snuggle and talk about everything and get along amazing... we even go for lunch and coffee occasionally.... he never treats me in a way that brushes me off or makes me feel unwanted... but our relationship from the outset has been based on sex... but now I’ve got feelings for him....

So does this make us more than just F buddies?
