Dear His Last girlfriend,
I honestly wish i could be you right now. Your fiance' is an amazing, amazing, guy. I'm only young, but he's not like most guys. He actually texts you back. He actually cares about what you say. He has morals too. He's not like most guys, who only want one thing (and we all know what that is). Hold on to him, never let him go. And one more thing: don't you ever, ever hurt him. Just because he broke my heart, doesn't give you any permission to break his. He deserves better than that.
Best Wishes,
His First Girlfriend
