POST EDITED BY MNHQ TO REMOVE IDENTIFYING DETAILS
I've been separated 7 years. For the last 4 years my 9 year old daughter hasn't wanted to sleep over at dads which has been fine.
Last year he moved in with a lady with 4 sons and they have convinced DD to sleep over.
I have concerns over the fact that the sons are 13,11,8 and 1 and she doesn't her own room.
My biggest concern is that her abusive (verbally to me) has now "blocked" me on his phone meaning I can't ask if she's ok or communicate about her in any way.
I don't see the point in her staying over as they live so close and don't utilise the time they have with her when she's there (just watch tv or sit in the garden) there's no value add to the situation
Also, the boys. . The sleeping arrangements and finally the lack of communication and being totally cut off. She hasn't stayed away from gone for 4 years and if she's scared I haven't a clue
