What Do You Do?

What do you do,
When he's all you need
When you want him by your side
For comfort,protection.
But you can't have him.
You can't have what you need
Can't have him by you're side
No comfort,or protection.
What do you do,
When he breaks your heart
But you still want him
You don't know why
But you still do.
WHAT DO YOU DO?!
