I've not posted in your sitch before and I haven't really been following either. But I had a question about your H taking the kids for overnights. I want to know where my W is staying if she ever takes the kids overnight away from home. We are not at that point yet; but could be headed that way.
Have you ever asked to see where he is staying? Just so you know where the kids are and the conditions of the place and surrounding area? If you have, has he just refused to divulge? Just curious.
