Hmm Married for 33 years so yes pretty serious relationship..
Good question ... I think I have a pretty good answer for you...
Lets see now... we split up the work pretty evenly.. I drive, she does not, I shop, she does not, I cook, she does not... She does the dishes, the laundry, I cook for the dogs, we share the rest of the care for them..
Oh yes... one more little thing... She decided a great many years ago that we would make love each day, every day... She enjoys it, I enjoy it, we both very much look forward to it.. A relationship like this one that continues after 33 years of marriage... is as rare as it gets and I am VERY aware of this.. So. to what extent do we need one another? I would suggest a great deal actually.. A relationship like we have is I might suggest so rare as to be considered irreplaceable...
Respect is critical.. I can do things she can not do, She can do things I can not do.. Together we do things that alone we could not do... I am a sailor, I am not only experienced I am skilled at all aspects of owning and maintaining a boat... I know my limitations of what I can do and what I can not do and I work to expand my capabilities.... Some days I sail by myself, most days I do not do so.. I prefer company when I sail....WE prefer not to sleep alone.
