TBH, I would never have separated and gone with the 50/50 arrangement at my girls' ages.

I'm lucky that my ex-partner is a shiftworker so can't have them overnight during the week. He either finishes really late or he has to be up really early in the morning.

What works really well for us is him seeing them every day for short periods and for overnight stays on the weekend. If he's on a late shift, he takes DD1 to school and has DD2 for a few hours in the morning. If he's on early shift, he picks DD1 and DD2 up after school and they have dinner at his place but sleep at my place.

We sort of fell into this arrangement by accident because of XDP's shift work but it means the girls see him every day and they have the stability of always sleeping at my house on school nights.

Would something like that work for you if your ex was able to rejig his work hours so that he could leave work early and have them for dinner each night? If so, I think it would be worth staying in your current location to avoid the 50/50 custody arrangement and to avoid the weekend only arrangement.
