I have seen many couples plod along , but living more and more their own lives . Often the wife has worked part time, to suit family needs. As the children have grown, she has had chance to branch out , follow her interests, and develop friendships and work round to be able to fit in her interests, driving herself around. Then husband retires, having given most of his attention over the years to his work and colleagues. Can have moved to a higher level. Once retired, does not know what to do with himself. Expects his wife to now spend all her time with him, give up her routines totally, and now run her life round him. If they had a good relationship, then they could negotiate ways to accommodate each other, but if he thinks that she is going to give her hard won life and friends and hasn't made any attempt to think ahead or talk about the change in their lives, it may be the final straw. When you have put the family first for years, and then see that he expects to do as he pleases, not make any effort to share chores, you think it is time that I did something I want to with my life. Usually when they make no effort to do anything , ask what is for dinner etc, you think that is enough. No wonder.
