Why she deserves diamonds

My ladyfriend, Christine, has taken care of me, or at least watched over the care of me, since I went down with my angioma last fall. She has done so, in spite of my attempts to either die or come out braindead, with a cheerful attitude and a smile.
I cannot tell you, or her, how much I owe her for all her hard work.
Let's just say that the biggest diamond I can ever afford is barely sufficient compensation for what she's gone through.
I would spend the money on anything else she wanted, but that seems to be her lust object in this world, so I'm happy to acquire one when I can afford it.
Know that I will take the best care of her that I can, no matter what it takes.
She's a very special woman, and I'm extremely lucky to have her in my life.
