Martin, although I agree with you to a certain level, but not with everything. “Love or no love” is just an illusion most of us have in our minds. And, after working with quite a number of people helping to get rid of this illusion, I can say that it looks differently for each person.
There are more crucial factors than just physical closeness or “MasterPlan” to a relationship. The key one of them is an emotional connection, which takes different forms and requires different behaviours.
