Romance can be as simply as holding hands--sitting in front of a fire--snuggling on the couch--a candlelite dinner (make it a simple meal, doesn't have to fancy)--watching a storm--a horse drawn carriage ride--a candlelit bath or soak in a hottub--watching the sunset--walk along the beach.
Romance cannot be learned. I can't really claim to be an authority on the subject but maybe you might wish to combine honesty, sincerity, passion, caring, and the courage to reveal your thoughts. Another thing I've discovered is that romance cannot and should not be rushed or forced.
