Every time you think you don't make me happy just because I am not happy, remember this:
"What I want to say is I owe all the happiness of my life to you. You have been entirely patient with me and incredibly good. I want to say that - everybody knows it. If anybody could have saved me it would have been you. Everything has gone from me but the certainty of your goodness."
I wish I could give you my own words but these are the best I've found to describe it.
