micromance

A micromance is an instance of affectionate care shown by one partner to another, often in little ways rather than as a big extravagant gesture.  Forget the big bunch of red roses — just make her/him a cup of tea.  These small moments of thoughtfulness build a thriving relationship more surely than a one-off big display. They are moments of authentic feeling rather than hackneyed conventional rituals.

Micromance then becomes the name for this style of nurturing and care.
