I live with and care for my 87 year old mother. I have grown used to her taking me for granted and treating my surviving sibling and even her dog better than she treats me. She is totally unappreciative. I found out today that she has betrayed my trust by revealing to several people what I told her in confidence. I’m so upset and hurt and angry. I feel like moving out and leaving her there to fend for herself with my sibling’s help. I won’t do that of course. I have too much character. So unnecessary.
