Self-respect.

You won't get any respect from others unless you have it for yourself.

You treat others the way you want to be treated.

And Gabe just got a lesson on how you will be treated.

I know how much you must be hurting, but remember that you need a person in your life who DOES get it, who DOES respect you.
I hope he gets his head out of his a$$ soon and DOES THE WORK HE NEEDS TO DO to be that person. But, if he doesn't, then he doesn't deserve you.
