Your comment brought tears to my eyes. I am so sorry you are experiencing this. I broke down in huge deep sobs when I first experienced this; it runs so deep. It makes you feel like you have just wasted decades of your life with your spouse. My husband doesn't call me by name. Not even sure if he knows it. The kids made him a picture book with names to help him hold on to some memories. I'm not one of them. He handed the phone to me to talk to his sister referring to me as "the person I'm talking to. In my experience, this lack of recognition doesn't come and go; it is gone and the quicker you accept it the better. I am a stranger -a friendly caretaker. Nothing more. It is hard to keep loving a person who doesn't know you. I took my marriage vows seriously. For better or worst; but I didn't realize how "worst" it could be. I am so sorry for how devasted you are feeling. It is a crushing blow. I think only people who experience it can understand how very painful it is.
