In short, ex from 2 years ago has never really left me alone. I ended the relationship and had a torrid time after when suffering a miscarriage with a pregnancy I didn't know about until after I'd told him it was over.
I've had messages occasionally over the last few years and haven't responded, he's blocked on all communications with read receipts etc so it's only on text that he can access me (and he doesn't know he can) I have kept it this way as I feel safer knowing if he's "around". Last week he created a new fb profile, liked a picture of mine that is public and sent me a message. I immediately blocked him without responding. Since then I've had text after text and calls to the point I've now blocked his number completely though I can still see his calls on my log and texts in my blocked messages. There's nothing threatening in the messages, all of them just asking me to at least reply (which I know is all he wants) and saying that we need to start again and he's sorry for everything.
He was my first experience of a narcissist so I fell for it hook line and sinker, knowing what I know now it was typical, love bombing, future faking, devaluing etc. Unfortunately for him I clocked on so we never got to the discard stage.
The point of this post is that although I know he wants a reply, that it would feed him, I'm struggling so much with not responding. I want to tell him there's no chance of him ever starting again with me and that I know he's full of shit but I also know that will give him what he's looking for, a reply!
If I stay quiet will he go away? Has anyone had any experience doing this and do they ever leave you alone?
