I have just found out that my mum has not told my aunt or uncle about DS.
This is because she doesn't want my grandma finding out about him because of the way she treated me and my siblings, basically we where never good enough for her and should have been more like my uncles kid, and the other one who she coo'ed over and bought lots of presents/gave money to etc when she gave us diddly squat because we where not good enough, and she panders to the other ones kids and has tonnes of pictures of them (the other one being the child of my uncles ex who is not a blood relative).
So as I can't remember her disapproving of me (I do remember it not being fare that she gave my cousin who is well off, money for uni while my family struggled) I have decided to stay out it but am I wrong to do so? should I say something?.
