DEAR ABBY: My wife died of cancer four years ago. She was my best friend, and the pain of losing her was more than I could cope with. I was in a fog for about two years, just going through the motions. Eventually the fear of spending the next 20 to 30 years alone drove me to try internet dating. I met some nice women and some very strange ones, but nothing came of it. Then a year ago, an old friend introduced me to “Elaine.” We hit it off immediately. We share the same interests and offbeat sense of humor,
