Pre break up coping mechanism

[Suspect]

Living in the same house but can't stand the sight of him or his whining. We have 3 gorgeous kids and all he does is moan about how much he can't cope with them. I can't wait to get away from him and start enjoying life again. Unfortunately this could be a good year before that happens. How the hell do I live with this man and not end up killing him.
I was up with kids at 6:30am. He didn't get out of bed until 10. Been on the sofa all day while shouting at kids to be quiet, then he went back to sleep this afternoon while I run around cooking, cleaning etc

Don't do it and I didn't!

If you can't put up with it a second longer how do you expect to for a year, why would you?

didn't want to read and run.
Is there no way you can look at leaving/divorce sooner than a year?

Disengage emotionally.
Move out to spare room if possible. Make excuse such as "This mattress is making my back sore" or "you snore like a wounded wildebeest" if avoiding confrontation is essential.

Why wait a year? I thought I had to wait until my children were older but now I know how to be happy again and therefore have realised how unhappy I was, I wish I'd gone sooner. Be brave. It will be worth it..

Why do you need to wait? Don't waste yours or dcs happiness. Ex and I decided to split up after a rocky summer in the October but said we would keep it to ourselves and not tell kids until after Christmas but after two weeks I couldn't bare living the lie and lying to the dcs. So he moved out start of November. That was over two years ago and we are all happier now and ex has better relationship with dcs
