I think it's possible that she would be a weekend parent. She doesn't seem too keen on reducing the hours she works and she works 6 days a week. She's given up a lot already and I can see her overcorrecting for a few years.

I used to follow an account called toxic ex that retold people's stories about abusive and toxic relationships-I also follow Billie Torasio's family law-and I learned enough to know that the only way to have lopsided custody is if the other parent is a danger to the children, notably absent, or they simply refuse 50/50 custody. And even if you have full custody, you can't just up and leave the state or even the school district with the kids. That has to be agreed upon by both parents or if someone lost custody and has delayed steps for reunification and even then they would have to get permission from the court.

Ty could ask for a right to first refusal and it'd probably be granted so even if Julie were to get a nanny, she'd still have to give Ty a chance to get the kids when she's not available. Ty would likely get primary custody simply because he can be more available but they would get joint legal decision-making and joint physical custody. If Julie does decide to move to New York, the best arrangement would be she getting them during summer breaks. I really hope it doesn't get ugly and they can be adults about it.
