Every place in the world have people that we think are kind and not really caring but at least willing to take a moment to listen I think you have just been used by someone as a convenient babysitter and from the sound of what you say and write he will be the biggest loser here as it is his children that will suffer from your companionship. If it is forever I sincerely hope they remember you and make the comparison between you and him, there then will be the winners so forget this fool and live with your memories of a better time spent with the kids. Let the fool fall on his own sword.
