Personally, I think you sound like a treasure. Give him yourself, but don't hesitate with the gratitude. He chose you. It doesn't make you weak, or devalue you, to be vocal in your appreciation. Relative worth has nothing to do with it; we're all so unique. But choosing someone, eyes open, is about the greatest gift anyone can give. I know he won't be sorry.
