A thought -- instead of trying to "fix" the communications issue which obviously is causing problems, would it be possible for you to say "I will speak to no one from DAMM's camp except his lawyer." Apply for a restraining order in
county against ex SIL and GF. The fact that he cannot speak with you is HIS problem not yours...why should YOU be the one having to put up with calls from hostile "strangers" because he has a court order preventing him from threatening you. He and his cronies have shown they can't play nice, I would think you would have good success in your county with this. That would force him to communicate only through official channels and would depersonalize all this. If he doesn't have a lawyer, tough...get one. Not your problem...of course unless Judge Good Ole Boy says his lil buddy doesn't need a lawyer...
I can foresee problems with email in that (a) it gives him a direct line to you (regardless of having evidence, it still means he can terrorize you even subtly -- or get others to do so via email), (b) he can always claim he sent an email and that you didn't get it (by, for example, ooops making a mistake in the address so that it's undeliverable) and (c) it is bending over backwards to allow him access to you when he has shown he can't be civil.
The reason this came to mind was I was at the orthodontist's with my DS yesterday and a man was there, talking to the receptionist about the bill. She said something like "well call your ex and ask her about the coverage" and he said "I can't do that, you will have to split the bill and send her half to her lawyer" or something to that effect. he did not have her phone # or her address. It was obviously not a happy situation and the poor kid getting the braces wanted to fall through the floor, he was so embarrassed (dad was quite loud and annoyed). I wouldn't even give him the option of making YOU pay by calling your lawyer -- I would flat out say "the only person that I want communicating with me is your legal representative". End of story. And if the visitation is clearly spelled out then there is no discussion to be had. I mean, really -- it does not take a rocket scientist to figure out EOW!!
