Nre. A wonderful thing !!! It gives us good feelings all around. Breathless anticipation, the little unexpected things.
NRE a terrible thing sometimes too. We get so wrapped up IN those feelings because they feel soooooo good that we sometimes neglect the sure thing in favour of the new & shiny.
COMMUNICATE, COMMUNICATE, COMMUNICATE!!!!!
Tell her how you feel but don't do it accusingly. Instead say something like "when you do x I am feeling this way". Velieve me, this helps to diffuse a potentially loaded conversation BEFORE it becomes loaded.
