Back story, I'm the middle daughter, have 2 sisters. My Father passed away six years ago and even at 48, 49 and 52 we were all heart broken. He had been very unwell for a long time during which time our mum came to resent him and was often cruel. Immediately after the funeral (a couple of days) she stopped talking to any of us including grandchildren who loved her very much and grieving their grandad. Anyway fast forward it continued even though we tried and then one day I called round on the off chance to talk and she'd moved out! Apparently gone to live with her "family" over 200 miles away. We have no contact details for her, it's like she's vanished apart from a call she made to my son on is 21st Birthday 6 months ago. How could she do this?
