I think I see the problem: it's geared towards younger people that still believe in unrequited love: the "crush" as I.portant as this is to young people, as we age, we become immune to it. Most have their romantic affairs in control,one way or another.
With romance, we have relationships, engagements, spouses, affairs, or friends with benefits, to name a few. A crush is something we gave up having when we matured. So when we see crush on a meme, we pretty much blow by it.
I'm not saying a crush isn't important to you, but once you leave school, your priorities change. We try to replace them with relationships. Just as it's important to get a good math grade, it's as important to an adult to have a job, pay bills, and any number of things that drive us, day by day.
So, when you post about a crush, don't be surprised if nobody says anything. Your peers won't discuss it here and adults have left that part of their lives in the past.
