Wow! This sounds absolutely healthy. You have love to give, despite and amidst your grieving your sweet Attie. Your generosity in helping this little sweet Riley in no way lessens your love for Attie nor your respect for her memory. I know this must sound trite, but...."better to have loved and lost..." My husband has been teary for the past 3 days. I had NO IDEA he was so attached to Albert. What this shows me is that Albert wound his way around everyone's heart. Our grief is directlyproportional to the intensity of our love. Do let us know how it works out with Riley and whether you decide to keep her. (I'd place bets you do!) Thank you for your words.
