Sorry, Stealth, missed your post. I'm rambling something awful, sorry if i have offended anyone.
My point was that when someone wants advice on something important, i would have thought they'd put a bit of effort in to make sure their posts are understood as best they can be.
E.g. the OP is very strange. All of the following 'background info' should have been slumped in there. Not scattered all over the place.
Rose - are you asking why you should delete this woman from FB? Or delete the thread?
Please don't let your dd round to her house even if the mum isn't in. I can't imagine your dd would be able to relax, knowing that vile woman could be home at any minute. And i wouldn't enjoy spending time in someone's home - even if they weren't home at the time - who called me names.
Just invite the friend round to yours more often.
If she lives close to you, and you're worried about seeing her on a daily basis, ask the police to go and have a word with her. This will stop her confronting you. Surely walking by each other in silence would be better than hurling names at each other across the street each morning?
