I'm going through all of this right now and H wants 50/50. No way if I can help it. To hard on the kids to switch houses every few days. They feel like they have no settled home. At least this is what a number of psychologists etc. have told me. Currently we are doing what is called "nesting" and we are moving in and out of the primary residence. Not fun but easier on the kids than moving every few days. Have you looked at all of the options offered. They all pretty much suck. I truly think it's hard on the kids to be forced to pack up all the time. No one ever gets settled. It [censored] for you that your the dad and you are the one that's the good guy. Good luck!!
My brother and his ex do a 2-3-2 split and that is just nuts in my opinion. The kids practically live out of suitcases. My brother has to have the kids constantly remind him of when they're supposed to do the exchange. There's also a lot of confusion over homework and projects- which parent is responsible. My ex and I chose to do 1 week rotations (50-50 custody), we switch off every Sunday. Granted the kids would rather live in one home with happily married parents, but this has been a good compromise. The schedule is clearcut and there's no interruptions during the school week. No confusion over homework either.
