I am separated from my STBXH who is an emotionally and financially abusive controlling arse. He is meant to see our children EOW but makes excuses why he can’t, ranging from the driving - he chose to move 40 miles away, to not wanting to drive at night, to his flat mate isolating and there’s nowhere to take them, to he’s exhausted, etc. He has had them overnight once. Mostly he has them for a few hours and then all they do is sit on his PlayStation and he lets them eat shite. He doesn’t like to do two consecutive days as it’s too tiring. You get the picture...
However, he is also v controlling and goes out of his way to attempt to spoil things, changes plans at the last minute if he suspects I might have booked something etc. He FaceTimes one of them for hours and they game online. And he was texting me telling me where I’m going wrong, why are they still up, why have they had McDonald’s twice in a week etc. It’s without fail abusive. He manages to turn every interaction with me into a rant about how unfair it is that I’m divorcing him and what a horror I am. So I blocked him. 
I said email me.
He calmed down but the last couple of days has messaged me on FB. As usual it’s reasonable at first and then he gets into his set piece of how horrible I am. It’s like pressing play on a tape.
So I blocked him.
I said email me if you need to discuss the children, and copy in your solicitor because I’ll be sending your abuse to mine.
He still expects to FaceTime the children when he likes, although in reality it’s only one of them and in my opinion he winds him up. And also I don’t want my ex husband’s face looking around my house! He gets the kids to report on me and I caught one of them taking pictures of the inside of the fridge because he wanted to know what shopping i was buying!
So, AIBU to only communicate via email with him? And what is reasonable regarding FaceTime/phone contact with the kids? Currently they have a limit on their phone of 2 hours FaceTime max, and phones off at 9:30, which I think is more than reasonable.
Thoughts please.
