I don't feel terrible that my crush was taken away from me by my good friend and then he was taken away from her by someone else.
Was the crush gone forever, or were you just not dating?
She was taken away, so she is gone forever.
It's understandable to be upset when a good friend goes after your crush. Friends are expected to be open and honest with one another so having a crush taken from you by one can feel like a betrayal.
I'm fine, I just won't be friends with him anymore.
While I do feel sorry for you to experience what your friend did, I am happy that you're just moving on and not allowing toxic and unfriendly people around you. I do hope you find another friend that is more respectful to you.
