DEAR ABBY: My boyfriend is 18 years younger than I am. Our relationship hasn't been perfect, but I love him to death. Unfortunately, I'm going through menopause and have all the side effects. Long story short, he found another girl. It was just supposed to be for sex, and he told me he wouldn't get into another relationship or marry anyone but me. Well, he fell for her, which I warned him he was going to do.
