I don't know where you live but that's not how it works most places. I know lots of divorced people. They don't live together any more. The woman gets full custody of the kids for all the reasons I mentioned above, but again, it's more about what the kids want. Even if they choose to live with their mother the father does get to see his kids. But he can't continue living with his ex, and they both live busy lives and have other relationships, so he can't just drop in to see the kids whenever he likes. Which is why they decide on a schedule. That's how it works with almost every divorced couple I know.
