How it feels to have never been anyone's crush

I am a guy who's never been proposed during his entire lifetime. I had a long distance gf for 5 years, pretty long time but even there i was the one who proposed and was the happiest person in the world to have her, but after 5 years she just wanted to leave, long story short... She left and I have also started continuing with my life. But sometimes this thought comes to my mind, Nobody has ever told me they like me, or even looked at me that way. First kiss? I haven't even been someone's first choice. Maybe that sounds a bit depressing but it's more true for me than sad.

Sometimes our memories come back and haunt me, I've learned to survive through them. I've never really been into hookups and stuff, I've always believed in sharing a lifetime together, but it almost seems like there's no people around me who feel the same. Let me know if you come from the same kind of thoughts, would love to discuss.
