Housing when divorcing

I am planning to divorce my partner but I don't want to move out with the kids as I am the primary caregiver and I don't want to uproot them. My partner won't leave the house without a court order. I know when I drop the bomb on him with the papers he is gonna be pissed and I don't want to live in the same house with him. Will I get to stay here with the kids? We own the house. He pays for most of the bills though I do bring in money with my side business but it's a fraction of what he makes. Any advice? I want it to be smooth but is that wishful thinking?
