Emotional Separation from Mother

I have a very difficult relationship w/ my mother and uncle. I love them even w/ all the problems that they may have. I accept their problems, their depression. They have very difficult time building relationships, accepting the “other” as is. So, long story short , they cut me out of their lives. They prefer a life alone and away of the joy of their grandkids and building a future together. I stopped fighting back( and it hurts me that the only family that I ( and they )have cut us out). I send them my prayers and love. I am still concerned about them and their health. How should we deal w/ people that makes us suffer, when we still have so much to love and create?
