Whoever Dumps You is Obviously Insane

Your relationship is going great. No major bumps as far as we can see.
You both like each other plenty, you're compatible, and you don't get into very many fights.
So why would anyone break up with you?
Clearly, they'd have to be totally insane.
So if you hear those magic words - "let's just be friends - it's not you, it's me" - better not argue with them.
After all, who wants to date an insane person?
