Watched this show when it was on TV. It's very entertaining but now that I'm older I find it ridiculous the way Alec behaves. His character is so deeply insecure for a man of his age who has already had a long and successful marriage.
I think most middle aged men going out with a woman half their age would feel insecure - about the age gap and how people would view them and their motivations, and whether they could continue to make them happy. I think what's especially poignant with this series is that Anton Rodgers did exactly the same thing. I can imagine nearly all of the topics touched on it at least the first couple of seasons in this series he probably went through...
