There are some other attempts to improve "being romantic", called "5 languages of love". It's hard for stable couples to gather any stats, but for example, vacuuming the home without spouse's reminder can be much more romantic than all the points of the article combined with an evening with candles. Perhaps, those 5 languages of love can provide rough approximation to guessing what the other considers as romantic.

Whatever it is said now about men and women are same, different hormones "control" them. So perhaps ancient wisdom of men as calm receivers of alternative current of women emotions is still good. Men just need to find some channel for their emotions, like psychotherapist or God.
