Hi Rose83. It bothers me slightly that your post has been on here for a while and there's been no response, which may leave you feeling even more neglected and angry.
My feelings are, reading between the lines of your post, that your mother and yourself may be going through one of the all too common rifts that a lot of mum's and daughter's go through - have a look at some of the heartbreaking posts on here, they'll show you how soul-destroying a breakup between mother and child can be. Perhaps a more positive move would be for you and your mother to sit down with a cup of tea and talk about what's going wrong, and if this doesn't work after one sitting, then meet and talk again, and again until you both see blue sky through the clouds. No granny or mother want's to live a life without their own children or grandchildren involved in it. Life's too short for this angry posturing - a talk over a cup of tea and a slice of cake with a good dollop of forgiveness spread over it could work wonders
