Cape May County - I have been invited to an anniversary party for a couple that has been married for many years. I have been friends with the husband since high school. After the first few years, the husband has always had a girlfriend, at times a few at a time. There have even been a couple that he has had very long-term relationships with. There is no one including his wife and children that are not aware of this. I wonder what goes through his wife’s head having this party.
