Have name changed but been round a while.
DM has always shown favouritism to one particular grandchild over all other family members. Including over all children. Quite frankly it is causing a lot of heartache, resentment and ill feeling. DM will not admit favoritism, in spite of GC being favored with more time, more complements, never stops talking about this child. Also more money has always been spent on her, including living rent free with her (grand child is now an adult) and now grandchild will move into DMs house for little or no rent as DM lives with new partner. Any time children have tried to address this we are apparently just jealous. DM has other grandchildren who are definitely not treated the same, never have and never will be. It's not even the money for me. I have always even as a young child had jobs and been financially independent from a very young age. Its the blatant favoritism that is hurtful.
So what to do? This is just making me not to want to have anything to do with my mother. Which sounds stupid as she is still my mother. I am able to forget about it for a while, then something else happens and it all comes to the fore again.
