Love her more...EVERYDAY. When you truly love people, you'll naturally understand most of their needs without them asking or even you always asking them. You can only chose to ignore those needs you can't provide for them at that moment.
For every single moment you disappoint her, try to make it up twice or more. It is not easy, but loving someone is a continuous challenge we must always strive to conquer in order to keep it firm. chiboyamobi
