“You are my religion”
You better say it in the bedroom when things are starting to heat up to induce the image of you only caring about him/her. Do make sure they don’t find it to be blasphemous because, then, things can go very wrong and you don’t want that happening, do you?
“I thought you could not look any better and you proved me wrong”
This one here has to be the perfect compliment; unmistakably romantic. It says that you have always thought that he/she looked their best that last time but they look even better than that, breaking records and stuff! There is no way they would not smile at this one.
