My wife and I are in our early 40's and have been married for 19 years with two teenage boys. We have a good relationship including the sexual aspects. My wife has a very good friend whom she knows since childhood. They are more like sisters than friends. Her friend lives not too far from us with her two kids (girl/boy 12 & 8 years old). She divorced her husband six years ago and since then she has devoted herself to work (she's an attorney) and raising her kids. She's an attractive woman and men hit on her but she doesn't want a superficial relationship and she feels it would not be right to pursue a serious relationship because she worries that it would make her kids feel bad if she presented them with a boyfriend. Our families meet at least once or twice a week and my wife and her friend share a lot of interests and it's common for them to spend hours talking. I usually participate in the beginning of the conversations but soon make myself scarce because it's girl talk.
