Not sure where you are in the world but I would seek legal advice asap.
Oh no dipsh1t wont like being threatened. None of them like being threatened because they're timid little creatures who scare easily!! Absolute boll0cks it means you are standing up for yourself and not allowing them to walk all over you and dictate the terms. its the same bullsh1t I've read a thousand times and been through. My ex tried to dictate my terms about me moving out. After a few weeks I thought "what the f'ck am I doing" and started to make my own decisions and im happier for it.
There are 2 scenarios.
A. He agrees to all of your terms begs forgiveness will do what ever it takes to save the marriage and is willing to put the years of hard work in to do that. e.g. he realises he's made a massive mistake
B. He continues to act like a self entitled d1ck blaming you for his affair( which they all do) and refuses to put in any work to fix it.
If option B you need to think of yourself and your kids and your future.
Its horrible and the hardest thing you will ever do but why would you want to be with someone who doesn't want to completely be with you?
I'm sorry for your pain hope, I've been there and im still going through it now. All I say is that there is light at the end of a very long dark tunnel and its called MEH.
