I'm going to walk out on my friends
Do you think that's for the best?
They will be better off without me. I am always the problemmaker between us three.
You should at least tell them why before leaving!  Just walking away without a word is pretty rude.  Hopefully things go better with you guys in the future!
I get what you're saying but I just don't care what anyone thinks anymore.
Well, imagine it was the other way around. You'd at least want to know why your friend is upset. Why not try expressing your feelings before making the final decision.
