SS have been called by my ex partner, again. This is the 7th time now. He has never been able to get over our split 7 years ago and wont let me or my new partner get on. The last time he called them they advised him to stop wasting their time. This time they have opened a CIN. Is this enforceable or voluntary? I feel at my wits end, he has very little to do with the children but is happy to throw fuel on the fire and stand back.
