I personally express my feelings - love, anger, sadness, happiness - through songwriting and music. It's more of a personal thing for me - just putting my feelings into words - but wouldn't an original love song make a most romantic gift? I've written several love songs over the years, but I don't think I've ever shared them with the person(s) for whom they were written. Maybe someday I will!
There is no right or wrong way to express your love for others - the important thing is that you express it! Sometimes just being there with someone - sitting next to them, visiting them in their home or at the hospital, holding hands, providing a shoulder to cry on or a joke to laugh at - is all you need to do to show your love.
