Excellent, very accurate. I always talk this things with my partner. i Do explain her and bring it to the table, that right now its all easy and everything is natural but as time passes we will have to do efforts and work on the relationship or it will die and its not because we are bad people, its because relationships need to be nurtured. All the details and tiny things. The surprises and all that we love. The novelty you call.

We also need to be mature that some things are traded. For example you trade in mystery and you receive security because you get to know the person more everyday (well that only applies if you pay a lot of attention to your partner and you have intimacy which a lot of couples lose or never have actually).

I love these topic a lot, paid a great deal of years "studying" them.
