Try accepting them for who they are and how they live their lives. It would probably take a lot of fortitude on your part to keep your mouth shut and not criticize. My four children have not always lived the way I would like but I just don't criticize and let them live their lives. As a result I get along with all of them and they are always there for me when I need them.i just came from my 86th birthday celebration , they were all there and we have a loving relationship. Try it sometime, I think you'll see after a while when you show them you have changed they will want to be closer to you.

Have you asked him if he would let you have the dog?
