I'm going to end a close relationship to get over a crush
You want to lose a friend to get over a crush?
This friend reminds me of my crush all of the time because of what happened so it is just easier to end it so I can move on.
I think that you need to do what makes you happy then. If the relationship is not bringing happiness, it is okay to end it.
Do you think it is okay for me to fix my own feeling's by hurting someone else's?
Using others to fix your pain is messed up. If you want to get over your crush, then approach them and tell them yourself, not your uninvolved friends. You'll get to keep your social circle and maybe get a date.
