Romansick is derived from Romantic and Sick. Romansick is used to describe people or a situation that is so romantic that it is sickening to watch or experience.
I saw a guy propose last night at this nice restaurant. He went through so much trouble to set everything up just right for her. He even had the waiter bring the ring in a glass of champagne. It was so romansick.
