All of the above is excellent advice - great post.

It’s time to start The Great Detachment. This man is only thinking of himself (and potentially his d*ck) and he is under the illusion that he can just walk away from all his responsibilities at the time of his choosing and convenience.
Show him that it does not work like that when kids are involved.
Tell your family / families what has happened so everyone knows that this is the choice he has made.
Cook for yourself and your kids and eat with them then clear up and leave him to his own devices. Wash and clean for yourself and your kids only. Don't ask him where he is, what time
he is coming home etc. He wants to be single so make him feel single.
Start having strong but calm conversations about housing arrangements, custody, any shared bills, disentangling any joint commitments - please be as cool and calm and detached as possible. The anti depressants helped me with this so much, I hope they do the same for you. By the way I came off them
when I moved out - easily. Just to let you know that it doesn’t have to be a long term / addictive thing.
Secondly, start building up your support network. These are the people you vent and cry to - that are NOT him. I hope you have supportive friends around you, otherwise you can vent here.
The last thing to say, in the wake of all the hurt and disbelief that he can just implode your family life like this, DO NOT DO THE PICK ME DANCE.
No more sex with him if he suggests it.
That door is now closed otherwise if you leave it open, that will trash your self esteem completely as you may misinterpret the sex as a sign of reconnection and you will be more hurt when it inevitably turns out that it in fact meant no such thing to him.
Don’t do it. Ask me how I know.
Go for your therapy and prioritise it.
You can get through this. He doesn’t deserve you. 💐
