Should I still block?

There’s this “dream-ish guy” who is still friends with me, and we occasionally go on cool trips. He won’t be pushy about sex, and prefers to pay for everything.

It used to hurt, but I don’t want to let him go yet... even though it’s clear he doesn’t want a relationship with me.

I’m guessing in a lot of cases, I am just giving off an air of insecurity, and just not quite leveled up yet, also he is very desire-able (approached everywhere, all the time).

What’s going on in his head? Should I let it go? Or just keep him as a friend?
