Why it don’t exist for two people to love eachother guy and girl?

I’m almsot 30 and never met a guy that I like that likes me back. Never experienced love of a first boyfriend , first relationship where u date meet family, take pics , be in love, nothing.

it seems it only exists where guy likes you and girl don’t.
