I’m truly sorry for your pain and loss, this is an awful thing for you to go through, I can’t imagine what you did wrong to him and his family to be cast off by your family in such a cruel and heartbreaking way..you’re 91 years old and he hasn’t a clue what he is doing to his mother. I can only hope that he comes to his senses because he’s setting himself up for a lifetime of pain and loss, he may not agree with that but he’s obviously very confused if he feels that this is acceptable. I hope that the rest of your family can help to support you during this difficult time,, I will pray for you to get through this painful time and get back to your life, amen. 🙏
