...and that, good buddy, is a gift ! I used to feel that way toward my husband. Later in life, we do become very independent. Now I could go anywhere without ANYONE and it's a bit disappointing to me, ironically or paradoxically, that I can. I actually feel a bit sorry for myself that I'm so capable of being alone! When my first husband left, he said I was too dependent on him for my happiness. Even though I taught and took classes in the evenings, had many friends, worked outside of the home, was involved in social justice issues at the Church, etc., he still felt that way. I really never understood it. A person can have a great deal of individuality and internal independence and yet hate to be away from their spouse. I think it shows that of all the things to do in life, your wife's favorite thing is to be with you!
I have dear friends who were fortunate enough to retire when he was 55. They married right out of high school. This couple could live in a house, but they have a 5th wheel and travel around the country and come back to CA for months at a time to be near the kids and grandkids. I would say they're together ALMOST 24-7. Their relationship with each other is simply lovely! In turn, they are the kindest, friendliest, most caring people, fun-loving, out-going people to their family and friends that I know, and everyone wants to be around them. I think it takes centered-ness (and I might add, a little money and a little luck health-wise) to achieve this, but I've seen it in action!
