This is so terribly hard

Why is his family acting this way toward you? You were his partner and the person he wanted to be with. I don't understand why they would shut you out at such a sad and tragic time. I am so sorry you are going through this without support. I have no advice to give. I guess you just have to try to let their behavior pass. Maybe they are grief stricken and not thinking straight. There is no sense in getting yourself sick over their actions. I guess if I were you, I would concentrate on doing what I could for my partner as far as what his wishes would have been and maintaining a closeness with him even after he has passed. He sees what is going on, I believe, and I am sure he is not at all pleased with it. He knows you loved him and that you are suffering. Have faith that things will end up OK. I wish there was more I could say. I hope one of your friends comes through and is there for you at this time!
