Beaut no he can't do the things he used to do!! Neither can you! He needs to grow the fuck up (sorry for the potty mouth, but actually not sorry)
I have no advice on how to get through this, other than to say I promise you will get through this - with or without DH.
In the past I was in a dreadful relationship (domestic violence, emotional abuse). I left. It was a case of getting through the day one minute at a time. I won't lie - it is exhausting living like that but it was the only way I could manage. Focus on your beautiful babies and gather your strength from them. Twunt face will probably put in an appearance in a day or so full of remorse...so in the meantime think about what you want.
Do you want to try again? If so what does he need to do? You will need to spell it out to him as IME men are a bit thick when it comes to stuff like this.
DP you want to split for good? Again he needs to know exactly what will be happening?
Expect all sorts of bollocks from him. My ex couldn't fathom that he was a twat at fault, there needed to be a reason, something for him to blame.
I think I can safely say that we can all offer you practical advice, emotional support and if we could give you a RL hug we would.
Beaut, my friend; I'm Rachael, I'm married to Andy, it's been a privelidge getting to know you.
