Being romantic comes down to being aware. Although this list of romantic ideas is a great point to start from, it is in no means exhaustive. Just as each of us are uniquely wired individuals, each person needs and craves romance in a different way.
Listen and be aware of what your partner is saying to you every single day. If they bemoan a social obligation, surprise them with a special piece of clothing perfect for the occasion. Are they partial to flowers? Then go outside and grab a couple of blooms from the garden to put alongside their morning meal. Know they hate doing a particular chore or errand? Do it for them. Have they been running ragged of late with no time to themselves? Give them a day off and pamper them with things that refuel them personally: a beloved book, video game, spa treatment, trip to the beach, or home cooked meal.
Sometimes these types of romantic ideas go unnoticed - which can be a tad unnerving. If that's the case, give your partner a kiss and let them know you took care of things for them, or have a special surprise to thank them. Then, leave it at that. It may take a little bit for the act to sink in, but it your forethought and kindness will be appreciated as long as you are romantic because you care - and not because you are expecting a specific reaction in return.
