I’m blessed more than probably the average person and have been married to the same woman for 25 years, whom I still love very much. We have 2 beautiful kids that are both away and in college.
My issue is that I am constantly wanting to be alone.
If I arrive at the house first and am by myself, I’m not really looking forward to my wife coming home, because then I have to meet some of her needs as well.
I simply don’t want the responsibility of marriage anymore and want to take care of myself and not have to meet anybody else’s needs.

Is this normal?
If so, is it something temporary that will go away?
Should I fight it and remain in the marriage for the sake of our kids?
