Ask. One of the most important strategies for effectively showing someone you love them is to meet their core-relationship needs. So-many couples get trapped in what I call the "mind-reader-expectancy trap". This when couples just expect their partner to know what they want, when they wanted it and exactly how they want it.
Better to get into the habit of asking, following through and getting corrective-feedback, until you're both expert needs-meeters, specialized in your partner!
