It probably is best to end the business relationship with your sister. This isn't the first time you've talked about how it's not working any more. Family and business often don't mix.

Don't give up hope on your sister as a sister. Maybe right now you need some space. But, maybe if you weren't connected by the business it will be easier to heal personal wounds, too. And remember the things she said like you won't have a relationship with her kids, that's all episode talk.

Right now just take care of you and your kids.
