Been separated from DS father for several years. DS is 8.
Their relationship isn’t great, ex never stuck to routine, never prioritised ds. Their contact time was “his” time. Basically ex expects ds to revolve around him in the save way he expects the whole world to.
Lots of conversations over the years with ex, expressing concerns about the impact of his attitude. All fallen on deaf ears. His way or no way, he’s always right, everything is always someone else’s fault or responsibility- including ds.
How do I protect ds from the fall out? He often doesn’t want to see his Dad, I think he’s distanced himself sadly. Dad makes shitty comments, guilt trips ds(“you haven’t rang me for 2 days, I’m so sad”) and gets huffy and confrontational(with an 8 year old!)
I’ve always just reassured DS, he’s quite a sensitive little thing, given lots of love and hugs but managed to keep a strong routine and he’s a really lovely kid. He does well at school, is well liked by peers and teachers and everyone speaks highly of him apart from his dad 
Anyone have any experiences to share? I do speak up against ex btw, I pull him on his shitiness and point out how damaging it is but clearly as a narc he’s not gonna suddenly change his ways.
