How did you lose feelings for the more "important"/"worse" ex-crushes of your life?

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.
