"When you love someone, truly love them, you lay your heart open to them.  

You give them a part of yourself you give to no one else and you can let them inside a part of you that only they can hurt ---  you literally hand them the razor with a map of where to cut the deepest and most painfully on your heart and soul.

And when they do strike, it's crippling like having your heart carved out."
