Okay ladies advice needed !!

My fiancé has a court hearing against my sister in a few days because they got into an argument and he went to walk away and she attacked him (physically) she has told ALL our neighbors that he beat the shit out of her leaving bruises when he NEVER touched her... she has also sent people to his work to fight him because of her lies...

I am the ONLY witness that has seen everything and what it looks like to me is my dad and sister wants me to leave my fiancé

My sister has FILLED my dads head with a bunch of BS police orders she’s not allowed around my fiancé but she was in his work and all he said to the other work was “I’m going into the back” and he was loading up a cart and she came home told my dad that my fiancé made a huge scene in his work yelling at her etc...

Of course I tried talking to my dad and he believes her so he’s hating my fiancé more and more now because of her...

My dad said if my fiancé gets a restraining order against her then me him and the kids have to leave because that’s his daughter 🙄

Now mind you our father is very sick he can’t care for himself at all so me and my fiancé have been taking care of him and every time he’s admitted in the hospital we are the only ones there not my sister she also stole his bank card before too

I told him if I did all that stuff she pulled he would have threw me out on the streets again like last time and he had no response at all... he’s been being very lenient my sister when she doesn’t do a damn thing for him....

It’s like they want me to leave my fiancé because of him and my sister hating eachother.

The fight started because he doesn’t want my sister around our kids because she had cys in her life for 4yrs for child abuse and neglect etc... she some how got away with it and my sister doesn’t respect that and neither does my dad...

She comes up here and takes my son whenever she pleases and doesn’t tell me at all... I had my neighbor watch my son the other day because I had to take trash out and I turn around she doesn’t have him and she told my sister grabbed and ran down her house with him...

We are number 7 on the waiting list for an apartment up here cause I wanted to be close to my dad because he’ll die if nobody is here to care for him I know my sister won’t but my fiancé wants to move to Ohio and I told him I didn’t want to do that yet because we aren’t prepared for that... like I want us to save up for a vehicle and get furniture and all that first before moving somewhere else...

If we move to Ohio would it be wrong for me to cut my dad and my sister out of our lives after all the pain they’ve caused us ???
