I know for me it is hard to establish these boundaries of limited contact when you have school aged kids, especially during the school year. There are invariably school functions to attend and just the regular shuttling them back and forth between parents which results in contact time, even if it is limited. I see my STBXW on an almost daily basis and that has made it more difficult to detach. I agree that it is better when there is less contact time, it's just hard to achieve that with kids in the picture and when you live in the same town only a couple of miles away.
