Less than you can ever imagine.

"The worst way to miss someone is when they are right beside you and yet you know you can never have them."

I know how they feel.
It sucks.
To know that what could have once been yours will never again be.

You learn to live with the almost empty feeling.
Almost empty because they're not yours, but are still in your life.

You cope with the fact that you made a mistake and you have to live with it.

So when you that chance.
Don't let it go.
You'll regret it.
