Love is a practical thing
One of the last things my mother said before she died was 'Love is a practical thing'. I take that to mean you must take action, you must live the life you have chosen, drink it fully get involved and make it better.
If you love your wife or husband, you must show that love, do that love, and make it work. It doesn't work on some subtle level. Love works because you do it. Then it permeates everything.
