I realize it is exceptionally tempting to involve your pals with your dating life.
Your friend may or may not have meant well. But either way, it backfired.
And if your friend (or any of your other friends) tries to butt into your crushes and any other relationships, you need to stop the gossip train right there. Change the subject. Log out. Walk away. Whatever it takes.
Your crushes and your love life are between you and whoever you crush on or even enter into a relationship with. Your friends aren't a part of the equation. At. All.
As for right now, if I were you, I would operate under the assumption that your feelings for your crush are currently not reciprocated. And that's okay. You have your whole life to have crushes. The vast majority of them will be quick emotional hits with no reciprocation. It's not nasty. It's not a rejection. It's not you being somehow unworthy (I'm sure you aren't).
It's just life.
