Anyone split with partner but still living with them?

[Unconventional]

I can't be the only one? (I'm a namechanging regular btw)
DP and I have been together nearly 10 years but in the last few months have decided to split for various reasons.
This was mainly my decision as I'd fallen out of love with him years ago mainly due to his emotionally abusive behaviour. We've got into so many negative patterns of behaviour with each other that it's become unfixable, and frankly I don't have the energy or the inclination to try to fix it. He wanted to try to fix it but seems to have accepted that I don;t want to.
The problem is, he won't move out because he can't leave his children (aged 5 and 7) who he adores and they adore him.
I can't move out as he'd never let me take the children with me and there's no way I could ever consider living without them, not even temporarily.
So the problem is, we're stuck living in the same house (and in the same bedroom for the time being) while not being 'together'.
Can this work? we get on ok on a day-to-day basis as friends so the children aren't living in a war zone.
Anyone got any experience of this sort of situation?

Basically by partner split up with me. Im 6 months pregnant. Things dont work out. When we have a slight disagreement he goes in a mood where he dont talk to me from 3-7 days. We live together. He ended it and still living here. I told him indont want him here as its just rubbing it in my face where i love him to bits my DD calls him dad as he took my DD on. He says he needs to save before hes going. I told him i dont want that as its unhealthy but apprently im thinking about myself and making it about me. Cant talk to him when hes like this. Hes now saying im the one who wanted a baby and kept going on about one… but it takes two to tango?!
