Here's a nice way to think about your situation. Being called beautiful, sweet and adorable is too specific. Your boyfriend probably sees you as more than just beautiful, sweet and adorable. Amazing is more general! He's trying to find one word for all of the great qualities you have. This is what the word amazing means to me "Something that is so wonderful, it is hard to find the words to match. Something that makes your heart beat faster or your heart melt. Something that tops everything else, and always crosses your mind."
Don't think too much about it. If you're happy with him I don't think being called amazing is the worst thing.
Best of Luck :)
