DM, 89 very soon, has just been diagnosed with Vascular Dementia. DMIL died last year with the same thing.
I've always had a difficult relationship with M, who effectively abdicated all childcare to my DF, who to his credit did a fabulous job.
She's cold, rude and I have a sense of responsibility towards her but have always managed great boundaries. I know though that those boundaries are most likely going to be eroded and I'm dreading what the future holds for her and me.
