A couple of months ago my mum and sister had an argument, they are both at fault tbh. My mum has since tried to apologise but my sister has refused to acknowledge this. She has deleted my mum from fb, ignored my mum's birthday and even ignored her on the street. They live two streets away from each other so this is incredibly awkward for all.
Me and my dad have tried to keep out of it, refusing to engage with it all etc. My mum is distraught, she suffers from depression and me and my dad are both worried how this is all affecting her. She hasn't seen her grandkids in weeks.
My sister has always been very self centered but she has got worse recently. She blames everyone for everything but this time she seems to be enjoying the fact that my mum is upset. For example laughing that my mum will not have anyone over at Xmas (Xmas is a big deal for my mum). Shes telling people lies about my mum.
Honestly I'm just sick of it all. We are trying to leave it for them to sort out but my sis is making it very hard. She's constantly ringing my dad asking him to take her places and asking him for money, which is obviously putting him in a difficult position because she is his step daughter. She has even invited everyone but my mum to my dnephews football game.
I just don't know how to handle it all.
