I've got to concur with darkness here. You took your next step to an extreme. You went house hunting 3 hours away, told the kids, talked to the kids about moving in with you without speaking to their mother first?! I know she has broken the family up, but those are her kids too. You may not respect her as a W right now, but you need to respect her as their mother. Was what you did in the kid's best interest?

I agree, it's great you took some action. looking around within a reasonable radius where you can effectively share custody of the kids would have been a great step. Then you sit down with W when you come up with a reasonable and fair plan. Then you sit down with your kids.

I encourage the forward action, absolutely. I have been an advocate for you getting out of that house. But do it in a way that is beneficial to the kids:)
