This is a tricky one. I’m sure many people will say block, block, block. But I was married to an angry narcissist for many many years, so I understand the fear.
Im currently divorcing mine and nearly every interaction with mine is ‘I hope this doesn’t piss him off”. There’s a lot of things he can still make difficult for me, so much as I’d like to tell him what I really think of him, I don’t.
Im lucky that mine now has a new girlfriend for his ego supply. A narcissist doesn’t like being discarded, although they’re happy to do the discarding.
Can you hang on until he’s loved up?
The other thing a narcissist doesn’t like is letting on what a shit rag they really are. My ex doesn’t seem to want to spread bad stuff about me, except how he feels sorry for me and my poor mental health. He instinctively understands that to keep his lovely reputation intact, he will seem less lovely to others if he bad mouths me.
Is there any chance your narcissistic won’t spread this private information if it will be seen by others as a revenge tactic?
I think on reflection I wouldn’t actively block, just simply stop replying or use very minimal replies, yes, no, Thankyou, busy, busy again and grey rock, grey rock.
I suggest this because blocking is an active thing on your part and they often react explosively and rage at things like this. He may then do or say something which he realises later reflects badly on him. He won’t care the effect it has on you.
in my case my solicitor has received emails, obviously sent in anger from my soon to be ex, only to be followed minutes later by a more measured response and asking for the earlier email to be ignored.
If you don’t block, you will be able to see what he’s doing and can do damage limitation if he decides to go nuclear over being discarded. Eventually you will get to a place when you will feel comfortable about blocking.
Others might read this post and think I’m seriously overthinking this and you should just do what you want.
But this is what a narcissist does to you. They turn your brain inside out and move into your head on a permanent basis.
