My wife is in the late stage of 5. She still talks some but 80% of time I do not know what she is talking about. I just agree and move on. There are no conversations anymore. Her family calls infrequently now. I am trying to to keep in touch with friends and family but it is hard to do. She leaves me a little at a time and I die a little at a time. Death by a thousand cuts i guess. I too work a few days a week just to get away. I have a caregiver for those times. Does she still recognise you? I think when she quits knowing who I am I will place her in a memory care. Probably sell the house and rent apt. nearby. I will still see her but I will try to start enjoying life a little. I am not sure if my guilt of doing this will let me or not. anyway, I am in your boat also.
