Hi, I'm not a solicitor. I'd recommend you read 'Family Law by Slater and Gordon' to help you understand what divorce is really about. I found it enormously helpful.
It is not a 'fact-finding' mission to determine fault/apportion blame.
It is a set of arrangements to separate the finances fairly (the trickiest bit), to ensure the needs of the children are protected (sometimes a tricky bit), and to "legalise" the ending of the relationship, just as the wedding "legalised" the start of it!
It is nearly impossible to contest divorce, and UB/adultery is the quickest route. Adultery is harder to 'prove', UB is the easiest way.
The statements are between you, him and the judge. You do not need to tell anyone, and they won't be passed on to third parties.
If, however, there is something in there about child abuse or violence, then you should state that you refute x but state strongly that you have no wish to contest the divorce.
The reasons for divorce, who divorces who, make not one jot to the financial settlement ("ancillary relief proceedings") but you must state that you refute any harm to the children if this is not true or provable in anyway, e.g. you don't have convictions or a record of harming your children.
If you've thumped him = so what? I'm not condoning violence, or suggest you thump him, but it matters not one jot to the judge. His job is to end your marriage, and agree that there are reasons to. He does not prosecute. The police do that - so don't thump him!
I too am being bullied through the divorce, it's stressful and he is divorcing me despite him leaving the marriage without notice. I steamed for a day when I read what he'd written (it's long, factually incorrect and contains utter lies). However, it's a means to an end. The quicker you come to terms with that, the quicker you can move on (she says hypocritically!)
Divorce is because you cannot compel a person to remain married if they don't wish to. Marriage is a choice. Divorce is a process to fulfil that decision.
That clinical.
It's the emotions that we all suffer with - the divorce itself is largely a long bureaucratic exercise.
Do join us on my thread 'Dear STBXH' if you wish to write ranty letters to him - it's hilariously cathartic.
