Just like two halves of a vase will never become truly whole if they& #39;re chipped or cracked, two broken people will never create one whole, healthy relationship.

For those who took this the wrong way (as per Twitter):

It& #39;s a metaphor for two people each w/their own issues coming together & spending their entire relationship trying to fix each other/make it whole

...not referring to couples that go thru things together.
