I only like people who like me

I’ve only liked guys that show interest in me, and I’ve never had that traditional 'crush' experience and I’m not sure if that's common. And I’m scared I might be missing out on great people.

People often talk about liking people without there being any romantic exchange prior to that. For me unless a guy starts saying "I like you a lot" or "You are beautiful" or  something like that I don't feel anything. I scroll on dating apps and no one feels attractive.

Maybe my self esteem issue is causing this? Deep down I kind of believe that I’m not likeable so maybe, 'making them turn around by showing them my charm' isn't an option for me, and my system just shutdowns the emotion of liking someone before I realize?

Maybe It's a fear of rejection or uncertainty and my system shutdowns the emotion again?

Maybe I’m not meeting and interacting with enough people? 

Avoidant attachment?

I’m not sure. Does anyone have experience with this?
