It is painful to watch OTWO. We had to put my MIL into a nursing home last month. She will never see her home again.
It's not the watching her deteriorate in the nursing home that's so difficult. It's seeing her anger and bitterness toward her son. She tells everyone that he has stolen all her money and the reason she is in this predicament is his fault. (She fell, broke her hip and refuses to help herself get better.) She has dementia and maybe some of that talk is from the disease but she and my husband have always had a 'difficult' relationship. However seeing his face when she places the blame on him for EVERYthing breaks my heart. Just like you are a good brother, my husband is a good son.
Hang in there. You know who I am so, call me if I can help.
