Is it wrong that I want my two best friends to break up?
What is your reason for wanting this to happen?
They are so happy together and I get nothing out of the relationship
It is not nice for you to want to ruin a relationship because you are being ignored because of it. You should let your best friends enjoy their relationship and possibly find one for yourself. This problem seems to either stem from insecurity or jelousy.
Damn fine attitude since I came here to vent.
I am just trying to help you out. If you sabotage their relationship you might lose them all in the end. You can still be friends with them just try to figure out a way to do it without harming them.
