OMG...That sounds exactly like me and my Mother's relationship...except after taking care of my Dad whom she spent 50 years hating publicly and openingly humiliating finally passed away this past October...I was there to witness him taking his last breath at home under hospice care that I insisted on (since I had power of attorney). She acted like her cold, usual self towards me unless there was someone she needed to act like she gave a darn. I was use to here narcisitic behavior...but never understood it until a therapist explained it to me. I finally had to decide what was best for me and my mental health and that of my family to cut the strings and leave her out of my life. My husband hated the way she treated me, and so with his support I am no longer burdened by her badgering and belittleing me, and especially my Father who is finally resting in peace...at least from her. My Dad and I were very close, and I know she resented it. But when I look at my maternal Grandmother and how she was, it is easy to see where she came by the "mean" gene. It is difficult to maintain a relationship with my neice, whom she and my Daddy raised from an infant. My Brother no longer talks to me for whatever the reason...probably because he had a different relationship than I did with my Mother. Talk about dysfunction, and this is the Reader's Digest version...Anyway...I digress...I feel for you, and I hope that your issues are easier to deal with than mine have been.
