The answer to the fist question is yes. Right before we got married it was down to about once a week, we had been together 4 years by then. After we got married for the first 3 years it continued to decline but we were both very happy.... the problem starts very small and grows very slowly, but grow it does! With hindsight, i think we both had enough 'information' before we got married to know it would not work out, what we lacked was the wisdom and experience to *understand* that information.
The second question, sometimes i did wonder if she was just doing this to wake me up. But since then, several things occurred which means that cannot be the case. The most obvious one being her desire to sell the house, she has already had the real estate agent draw up the contract and she wanted me to sign it. Then my parents offered to sell their house, move in with me and buy my wife out of her share of the house. My wife said it was a good idea.... no women who was not absolutely certain about a divorce would ever think that was a good idea! So with the exception of a miracle of God, this is the one thing that finally convinced me this marriage is definitely over.
Yes our feelings toward each other do seem to have a certain similarity, the one big difference is i am open to examining and challenging my emotions, but she is not.
Now that i think about it, on many occasions we did talk about sex, she would always say she does not know why she feels that way. Exactly like me, she was trying to deny her real emotions.
in answer to the last question, i am a very affectionate person in my own ways, but not the ways she was looking for. I am a hugger, a kisser, tckler, a joker and even a random singer, kindof schoolboy juvenile ways of showing affection, that kind of thing. Even our friends would joke, "hey you two, cut that out in public". Somehow all that affection was invisible to her. Later when things started getting bad, any time i would try to show affection, she would spurn me, that went on for 2 years until she said it's over.
