Hi Feyth, my tip would be - make technology work for you. So, route his messages or whatever to a time and place where you choose to pick them up. If you close down the instant access to you, it really helps I think.
Also, only respond to constructive communications. Unpleasant ones - don't reward with a response.
He has really ramped up with the unpleasantness and do exercise caution in any direct contact with him.
