I say it to him often, but I could say it even more so. He says it with his eyes, and his touch, and every time he brings me something I'm too lazy to get myself. I say it when he's inside me, after he's come, after I've come, after we're both spent.
He says it, qualified sometimes, letting me know that I do make him crazy from time to time. That I have bad habits that get on his nerves. But those bad habits are just part of me, and they aren't dealbreakers. He loves me in spite of those things.
For the record, I said it first. And I'm really OK with that.
