So I (33F) left my STBX (45M) in early September. I finally gathered the courage to move out after he spent the morning cursing and screaming at me.

I moved to his country just a few months ago. Have basically no support system here. Ex is a manipulative narcissistic personality who has some deep issues that he refuses to get help for.

Since I left, he's become increasingly obsessed with speaking with me about our issues. It started as a plea for reconciliation. Now he's changed the tune and says he just wants to understand what happened. Thing is, I have explained all this to him ad nauseum but it's like talking into a void. He retains nothing from our conversations and just creates reality his own way.

So since I left I've gone no contact. Anytime I did make the mistake of responding in any way, he sends me a barrage of messages blaming me begging me scolding me thanking me it's a Rollercoaster.

Yesterday I messaged him in anger because he's been giving my number to his random relatives who are contacting me (with whom I have zero relationship). Since then he's messaging and calling relentlessly. He doesn't know where I now live (although he's been trying to find out from our mutual friends) but he knows where I work and I'm starting to worry he will come to my office with this shit.

What do I do to de escalate the situation?

I'm waiting for a few more weeks to serve the divorce papers as I've been travelling in and out of the country and his mother's first death anniversary is coming up, I didn't want to do this in the middle of that.
