I mean, crushes that you saw all the time and you were close with, and ones that weren’t good people. My ex-crush, this Polish girl I nickname “Helen” on here, turned out to be a Christian with internalized homophobia and was an ableist asshole who hated special education students and made fun of me behind my back.
“Time heals everything” is essentially true. You’ll eventually move on emotionally, and the people who actually matter in the long run will either remain good friends or be fond memories. The ones who don’t, you might remember with a kind of regret that they weren’t good matches for you, but you’re better off without them anyhow.
There are a ton of people in the world who all have their own specialness, and you’ll see that in someone else eventually, maybe in multiple other people throughout your life.
