He insessantly emails/messages my oldest, who's left an emotional wreck each time.

(Including, AFTER filing for divorce, sending an email to her for the express purpose of talking about how horrible I am and gaslighting her on things she's lived through. Badmouthing the other parent is expressly forbidden by state law, once you've filed.)

I asked him to stop (and CCed his attorney on this request), so he started bugging friends of mine to deliver a birthday present to my youngest.

Just want this BS over, but know it's only the start.
