I'm so sorry you are going through all this with your husband who is so ill. That's sad. I know it must be hard trying to cope with his unusual behavior. It is nice to hear that you love him and he still tells you everyday that he loves you. Your husband is probably frightened and realizes; even though sometimes it may not seem like it, that something is terribly wrong with him. My husband had lung cancer and died last July. The last few weeks of his life he was taking Prednisone and the side effects caused him to act oddly at times; frightened that I'd not return if I just went to the bathroom, waving his arms around for no reason etc. But we both loved one another and told each other that daily like you and your husband do. Hold onto that because there may be a time when you won't hear it again if your husband goes to Heaven before you. I know I miss hearing my husband saying I love you even when he wasn't quite right.

Prayer helps immensely. It did for me and still does. God is there for us. We can get through these times with God's help. I'll say a prayer for you and your husband.
I wish you both the best.
