Took a guys virginity now idk where things are

I took my best guy friend best friends virginity. Now I know that I have fell for him, but I can turn that off. I’m in a weird version of FWB with him. And I’m just wondering if it’s really possible for a former virgin to not get attached and just want a FWB (cause if he does have feelings he’s really good at hiding them cause we rarely text each other, he doesn’t really answer my text either also he lives like an hour away)
