I am not sure if my ex hub is BPD or not, but if he is, can I ask a question?

We have 2 kids and I don't mind talking to him with regards to our children.

But... He has remarried, yet still calls me many times a day.

I have told him to stop but he doesn't. I ignore his phone calls for the most part. Any suggestions?

Does he have abandonment issues?

Sorry if this is the wrong forum.
