My narc Ex has a new female friend with a DD the same age as our own. They all went for dinner together a few weeks back and my DD ended up having a sleepover at this woman’s house (it’s just her and her DD) My Ex and eldest DD went home to his. By the sounds of it it was very last minute, my DD had a great time and all was good. I was put out that my ex hadn’t told me she wasn’t staying with him that night but being the narc that he is he would inevitably have taken any of my concerns and snowballed them into something else..so I left alone. Tonight DD is having another sleepover. She was really excited to go and my eldest DD reassured me the woman and her daughter are lovely and not to worry in a nutshell. But I don’t know. I need some perspective. I think ex’s narc ways are making me back down over this but should I be asking for this woman’s phone number? To meet her? Is it any different to when DD has a sleepover with one of her school friends and my ex doesn’t really know the parents? My DD is incredibly vocal and had she not wanted to go or been worried in the slightest I would know about to. For confirmation my ex isn’t staying there. What do you think? What would you do? I need perspective please!
