A few years ago I saw a snippet of a documentary on relationships. It was a snippet because my daughter was very young, I was the main parent, and for years rarely saw a whole programme in one sitting. In this documentary a very elegant older woman was talking about inviting her husband’s lover to come and live with them in a bid to hold their relationship together. That was it. That was all I saw. This didn’t sound like desperation on the woman’s part to keep a husband to herself, but more a recognition that they were older, and the thought of ending a long relationship and everything that would come with it would simply be too much.
