Here is one on my orders that I fought for (Abbey)
I have two boys my ex's gf has two girls. They were living in a two bedroom house and I refused to take my kids to their Dad's because I have an order set in place that my boys are to have a room to themselves. Not to be shared with gf's kids. I think it is WRONG for your ex to even think that it is okay to put the two together. It's very much your business!!!
