I've been f* zoned, if that's a thing, several times. Where they 'suddenly' realised they didn't want to pursue anything further, however friendzoned I can't think of a time in recent years at all.
I previously did have male friends I spoke to a lot but sadly most of them ended up coming out with sleazy, inappropriate comments even though the majority were in relationships, and I realised their lack of respect for me.
I sadly don't have any close, straight male friends at present, I'm friendly with men but close ones, no, not through choice, just circumstances.
If you were close friends with a man but wanted more and they didn't, would you carry on as normal? Would it make things awkward? I'd be as nice as I could about it to them but I'd probably need a few weeks of distance to get over the crush, is that immature? Not ghost them forever, just some space.
