If someone tells you they regret laying feelings on you, how would you feel?

Would you question yourself, why did they say that? What is wrong with you that they feel that way? Are you such a bad person? Are you really a useless waste of space? It just kind of dawns upon you that you're probably the reason why someone is screwed up. And all you could ask is, 'What did I do? All I ever did was fall in love.' You ruined someone, you're like a disease, a plague, a useless waste of space. Maybe you deserve to die.

You're HURT. Confused and hurt. The wound is gaped open now and there's no way for it to heal.
