nm who tbh has already met dd a few times- initially by accident;
when ex has tendency to be extremely jealous (afaik he is still single and was still pestering me til fairly recently), completely unreasonable, occasionally still abusive and threatening, with a habit of making up nasty lies about other people (ie me) to suit his own twisted ends...
When to do it and how to keep it civil with minimal impact on the nm?? (i really don't want to but there's a part of me telling me that i should!) guidance anyone?
