My daughter thinks it’s my fault her father is in a coma

Ok so long story short I left my ex (daughters dad) because he was abusing drugs and didn’t want to get a job. That lasted four years of emotional torture towards me. Now I am happily engaged but now as my daughter grew up she’s 8 by the way /she’s starting to have hatred towards me by saying because of you you left my dad and now he’s in a coma. She’s also snotty towards my fiancé. What do I do! Need suggestions via /r/Parenting https://ift.tt/2KLCuos
