My husband took his co-worker to lunch and movies several times bought her gifts and calls her up and bought her child gifts, she is a single mom. He went to see her new house and writes her very "sweet e-mails. Should I be worried? We have been married over 30 years the co-worker is 32 and he says he is her mentor and she is a very good friend and they pray the bible together. Am I being stupid to be suspicious? Turtle
