You said you both know each other inside and out.
So here is some advice from the eastern philosopher Osho:
Quote:
LOVE IS NOT A RELATIONSHIP. Love relates, but it is not a relationship. A relationship is something finished. A relationship is a noun; the full stop has come, the honeymoon is over. Now there is no joy, no enthusiasm, now all is finished. You can carry it on, just to keep your promises. You can carry it on because it is comfortable, convenient, cozy. You can carry it on because there is nothing else to do. You can carry it on because if you disrupt it, it is going to create much trouble for you… Relationship means something complete, finished, closed.
Love is never a relationship; love is relating. It is always a river, flowing, unending. Love knows no full stop; the honeymoon begins but never ends. It is not like a novel that starts at a certain point and ends at a certain point. It is an ongoing phenomenon. Lovers end, love continues– it is a continuum. It is a verb, not a noun.
Once you are in a relationship you start taking each other for granted– that's what destroys all love affairs. The woman thinks she knows the man, the man thinks he knows the woman. Nobody knows either! It is impossible to know the other, the other remains a mystery. And to take the other for granted is insulting, disrespectful.
To think that you know your wife is very, very ungrateful. How can you know the woman? How can you know the man? They are processes, they are not things. The woman that you knew yesterday is not there today. So much water has gone down the Ganges; she is somebody else, totally different. Relate again, start again, don't take it for granted.
And the man that you slept with last night, look at his face again in the morning. He is no more the same person, so much has changed. So much, incalculably much has changed. That is the difference between a thing and a person. The furniture in the room is the same, but the man and the woman, they are no more the same. Explore again, start again. That's what I mean by relating.
Relating means you are always starting, you are continuously trying to become acquainted. Again and again, you are introducing yourself to each other. You are trying to see the many facets of the other's personality. You are trying to penetrate deeper and deeper into his realm of inner feelings, into the deep recesses of his being. You are trying to unravel a mystery which cannot be unraveled. That is the joy of love: the exploration of consciousness. - Osho
