He handled being along I believe at first very well. But his lonliness took over and he is now seeing some lady and lying to me about going out of town by himself and where he is going. My mother and father have been married 55 years. My mother has dementia but still knows my father is there and recognizes us. She is deaf and blind. And being lonely is a two way street- she goes to bed alone every day and night just like him. The only difference is she is trapped in a home and he is in the free world and has all the benefits. He cared for her until he couldn't lift her anymore. Maybe he thinks he paid his dues. I don't know. I had this picture of my dad my entire life until now - and I'm thinking he either pulled one over on me or he all the sudden turned into a different person. I just don't get it. And don't know how to handle discussing it with him.
