First the husband tried to make the wife his possession, and once she is a possession he loses interest. There is some hidden logic in it: his whole interet was to possess; now that is finished, and he would like to try some other woman so he can again go on another trip of possesion.
The word relationship is beautiful. The original meaning of the root from which the word to relate comes is exactly the same as to respond. Relationship comes from that word respond. If you have any image of your wife or husband, you cannot respond, and hence relate, to the truth of the person. And we all go on carrying images.
If you love a woman, you can dominate her. That's why lovers go on playing politics with each other, dominating, possessing; the fear is there that if you don't dominate you will be lost and the other will dominate, so they continuously fight. Husbands and wives, lovers, go on fighting; the fight is for existence, to survive. The fear is there, "I may be lost in the other."
Identification with the body, with the mind, with our possessions, with our families, with our friends - any kind of identification takes you outwards. All your possessions will be outwards: your wife, your husband, your children, your body - your body is outside you; your mind - your mind is outside you. The only thing that is not outside you is the witnessing. Just the watchfulness - that is your buddha. Identification means losing witnessing, falling into the trap of attachment. That is our misery, that is our slavery.
You have not looked at the poor woman for years, for the simple reason that marriage makes things so certain. Marriage makes things so dead and dull. Marriage takes all surprise and wonder away. Marriage makes you take your wife for granted, your husband for granted. What is the need to look at your wife? She will be there tomorrow and the day after tomorrow and forever. You look at people when you know you may not be able to look at them again. Marriage kills; it makes something tremendously beautiful very ugly.
It has happened, women have helped their husbands, sacrificed their whole lives, never thought about themselves. Their surrender, their devotion to their lovers has been total. In this totality, they have achieved before their lover has.
Only in sex the noise sometimes stops. I say "sometimes". If you have become habitual in sex also, as husbands and wives become, then it never stops. The whole act becomes automatic and the mind goes on its own. Then sex also is a boredom.
So the first thing to be reminded of: love is never a relationship. Then something else is masquerading as love. Maybe you are searching for a husband or a wife - you are searching for some security, you are searching for some structure. A structured life is a murdered life.
In every bed you will find four persons sleeping together. It is very rare to find a double bed, because then four persons are there overcrowding it. The wife is there and the ego, and the husband is there and the ego - husband is hidden behind his ego, wife is hidden behind her ego, and those two egos go on making love. The real contact never happens.
