Hi J4J
I can't tell you how sad I am to read that are simply, witht he exception of Waterlego, being failed by everyone who should have your back at this stage. Having said that, I have so much admiration for you in standing firm, even if it's hard work at times (which it sounds like it is at the moment).
Please disregard anything your H says his therapist has said. If you canot trust him not to knock you unconscious, you cannot trust him to tell you the truth.
I agree with izzy who suggested that you might be able to ask waterlego to act as a kind of spokesperson for you, someone who might be able to focus the attentions of those agencies who are supposed to be helping and supporting you.
I too would distance yourself completely from your H, his parents and (sadly) your parents. None of them have any business in your life unless they are ALL able to acknowledge and accept that your H's behaviour was INEXCUSABLE, COMPLETELY UNJUSTIFIABLE AND TOTALLY UNRELATED TO YOUR BEHAVIOUR OR MARRIAGE ISSUES.
Until they can all admit that and apologise profusely to you for ever suggesting you might be at fault, then they are toxic to you and your recovery and should be kept well away.
I would also reiterate laying down the law about contact with your children (at YOUR convenience, not your H's) and I would also seriously consider changing your number and only giving the new one to your actual friends (and not to your family, H's family, or H himself)
You can keep the old one and tell H that you will check it once a day for messages regarding contact. If he doesn't wish to call, he can email.
His continued contact with you, and drip-feeding suggestive ideas about what his therapist "said" is simply another (albeit more remote) form of emotional abuse. He is doing whatever he can to undermine you and the experience he put you through. PLEASE DON'T LET HIM
(Phew. Sorry, that was quite long. Hope you got through it!)
