Dear Annie: My youngest daughter, “Marta,” is beautiful and caring but intellectually challenged. I have always encouraged all my kids to do what makes them happy, and she is no different. A couple of years ago, she met a wonderful man through mutual friends, “Brian.” After dating for almost a year, they married last fall. We could not ask for anyone more caring and giving. Brian makes Marta his first priority as a spouse, partner and friend in his life.
