Sister trouble

Moo • British 🏴󠁧󠁢󠁥󠁮󠁧󠁿 an opinionated ‘96 baby with a university degree in animal behaviour and biology 🎉🥳

So my sister walked out of my family over a year ago and went to live with her biological dad. She has not only blocked me on everything but also my mum and my other sister. My mum did nothing wrong at all. Like my sister left because she couldn’t handle the fact that my parents found out that she avoided the responsibilities of looking after the dogs to go have a shag (we have a chih who has serious separation anxieties and can not be alone for hours at a time). And today I decided to message her. (I’ll post the messages that happened today). I don’t know what to do with her anymore and I’m so hurt. 😭 she’s claiming my dad abused her (he didn’t at all. She posted a thing on insta saying how she was psychologically abused for 13 years which is not true in the least). Idk if I should have been nicer to her but I’m just so done. What do you guys think?
