I'm going to cause drama between my friend and her boyfriend.
Why would you want them to fight?
I just like having drama in my life.
You really shouldn't mess up your friends relationships. It will make your friend resent you and probably other friends of yours, too.
Don't worry. She'll be grateful to me in the end.
I'm not too sure about that. No one appreciates having others stick their noses into their private relationships, and that extend to friends as well.
