WTBH,
I am so sorry. I know how emotionally draining the barrage of emails and texts can be. I am really surprised that the judge did not see this as harassment. But as you made a Freudian slip above in your first message, maybe he is a just a re-"asses".
Just keep documenting. It took almost a year for my harassment issues to be taken really seriously. Document the times he does not bother you also. Look for patterns. Try hard to keep moving forward making your and your girls life positive and he will have a slip up the courts cannot ignore.
When you meet for exchanges, make sure you have another adult with you, regardless of where it is if you can. Keep you phone handy and set up to film video, just in case it is necessary.
He is pushing a dangerous line, and he will make a mistake that will cost him. Just be ready for it.
I worry for you. Take care,
