We live in a society that judges women who date younger man but not men who date younger women. A when it comes to love. If dating a younger man has made you happy, then be happy. You are too old to worry about what other people might think of you, including your own children.
Not only did you choose to move across the country but you allowed your heart to be opened again. Most people never leave the areas that they grew up in -- so all your efforts to create the life that you truly love should be appaulded.
