Hello! OP here again, for some reason I can’t log in with my original username so I’m using this one again, just to update…
So, as you’ll see above, my stb ExH was removed by the police in Oct 2020 and has been living an hour away since.
I (finally) won my legal case
and the third of the children was diagnosed with ASD and his EHCP is going through. I’m still in the family home and he sees the kids overnight for on average one night a fortnight. 
The bloody divorce still isn’t finalised and he’s predictably been an arse. He doesn’t pay any maintenance but is covering the mortgage, which is a similar figure, and also means he can’t exert power over me the way he used to. Before I won my case he was also paying £120 a week for the children but on the weeks he picked them up to see him, he docked me £20 for petrol money. Seriously.
Anyway we have the FDR coming up (this is the first court bit, I think that’s what it’s called) and he’s submitted a Without Prejudice offer which, even knowing what an utter dick he is, was rubbish.
I don’t get it. I never will. He has bleated about avoiding court endlessly and yet has offered the same offer he put originally - a pretty much 50/50 split of all the assets and the removal of his premarital pension from the pot.
He’s arguing that his housing needs are the same as mine (how? He hardly sees the kids and he’s miles away) and that their SEN are not a problem at all and they will be able to live independently so no need for any special measures in that regard. All of this is without any evidence whereas I have enough reports and assessments to paper the walls, demonstrating the details of our children’s disabilities. He doesn’t even do parents evening.
He’s also suggested that we take out similar sized mortgages, despite his earning double, and is insisting that the family home is sold. One of my children can’t tolerate any change AT ALL and he’s completely discounted that saying “no child likes change”.
It’s weird. It is so far away from anything I would even consider. Why bother? The offer also had a few vitriolic digs about how he had a house when we married. So did I! But that’s been erased.
And finally, he’s repeating a narrative that it isn’t safe for him to be in the same building as me because he says I have lied about what he’s done and made false accusations. He simply cannot own what he did - the coercion and bullying and financial abuse, all of which is documented. I actually think he stays away because he doesn’t trust himself not to lose his shit entirely at me. He still sees fit to swear and rant at me given half a chance, “fucking slut” being his insult of choice lately.
Anyway apart from him being a dick, the rest of my life is really very VERY lovely!
If anyone has any insights I’d love to hear them!
