Dp's neice invited ds1 for a sleepover at Hera tonight with her 2 eldest children. Niece is the original shouty mum (gets on high horse) and some of her parenting techniques are not what I would wish to expose my children too (gets down) She has only recently moved into new flat after splitting with her partner. Her exp was abuse, and an alcoholic, his son is a bulky and bullied her other kids. The family have told her under no uncertain terms that if she goes back to him again then we don't want anything more to do with her.
Turns out that the exdp's son has been sleeping over and possible the partner too. We told her last night that ds1would not be sleeping over for the above reasons and asked her if they were back seeing each other, she said no but did nothing to convince us otherwise ( she is normally the kind of person who would argue black was White) On way home from picking ds1 up from school I saw her ex through the winder at her house.
Have now just had my niece on the phone crying asking me to let him stay as it's not fair on her and that she promisesthat the ex or his son won't be there.
I stuck to my guns and said no but I feel sorry for me niece. AIBU??
