Tell him my love for you is everlasting my feelings grow stringer for you everyday x
Say you love him so much n you never want to lose him he is the best thing in your life and you never want that to change n you can never live without him n you can't explain how much you love him x x x x
Say, hey guess what (then wait for him to say what) the say I love you
Just remember that "I love you" is so much better then "luv you" or "luv you"
Say , my love for you is like diarrhea I can't hold it !!
Just say it. Say " I love you (nickname you have for him)!"
