Sociopathic ex with DC

[Willowy]

I've name changed for this but basically I've split up with my ex who had narcissistic/sociopathic traits. I've done a lot of reading on this and he definitely sounds like a cluster b personality.

I worry about when my kids stay with him at the weekend. Ex has no empathy skills whatsoever, if the kids hurt themselves he is useless, he doesn't listen to them, ignores them in favour of being on his phone all the time and when asking the older child questions, he then doesn't let older child answer because he's too busy chiming in with his own answers and opinions.

He has no social etiquette, and never listens to anybody. I guess what I'm trying to say is he is emotionally stunted.

Will these things have an impact on my children's development? They are only young, oldest is in school, youngest still a toddler. The youngest is so loving, if anything the oldest one has started displaying outbursts of frustration and also cries sometimes when he has to go into school. He is probably upset over the split understandably, but I always ask him how he feels about things and what he thinks etc. Ex just seems to gloss over people's feelings so I worry about leaving the kids with him at weekends.

Sorry for the long post.
