What do I do now?

I look back and see the eyes of my old lover
looking back at me.
His eyes so sad I want to run back and tell him the truth,
that I really do love him,
and that I couldn't live without him.
But I fear that my addictions will hurt him,
that my temper will devour him,
and that my love will not be enough to satisfy him.
How do I tell him that I really love him,
and that I don't want to let him go?
I love him so much that I don't want to him hurt.
I'll hurt myself before I'd ever dream of hurting him.
But how do you tell the one you love that your going to die no matter how much you try to hang on to life?
