I have just heard that a very close friend's ex-wife has been diagnosed with AD at the age of 44. He has been divorced from her for several years and has two teenage children who live with their mum. When she was diagnosed, he moved back into the family home and feels 'emotionally responsible' for her - even though he has been divorced for years and loves someone else (whom he has told he feels 'guilty being happy'). He won't talk about it to anyone and I'm so worried that he will give up his happiness because of feelings of guilt. Is anyone here in a similar situation? Can anyone offer any advice?
