Why Is She Like This Anyone knows why?

I have no idea why my husbands ex blames me for all her problems. Well my husband has a 12yr daughter with her she won’t let him see the daughter for almost like 3yrs. We live in different states and my husband is in the military and he get deployed a lot. Well the ex every time my husband asks to see the kid she makes it about me. She says well our daughter don’t like your wife ‘cause now she feels you like your wife more than her. I know that’s not how the daughter feels is how she feels. I mean had enough of her ****. So I told her that I’m sorry you are a trailer trash, 7th grade dropout, unemployed, your kid don’t like you and you won’t let her have relationship with her dad, and your own parents ped a way not wanting to speak with you, but all that isn’t my fault. Why do you think she has so much hate I mean I never done anything to her.
