Money worries about going solo?

I'm finally really trying to build up the courage to end my marriage, and go solo with my 13 month old DD. I know I'm jumping ahead here but I need to try to get a clearer idea of how things might go. I'm hoping knowledge will give me the power to make the leap. Plus I want to do the best for DD, and I fear husband will turn on me as soon as I tell him (not physically). If anyone can help with any of these questions, or give me some advice I'd appreciate it!

I don't want to go back to work until DD is at least 2. My husband works full time. So I figure I'd get DBP, hopefully accom allowance, and child support. But I'm not clear - does the child support from husband just go to winz/ird to cover the dbp? Will I see any of it? could my husband argue that I should go back to work (I don't have a job to go back to though) so he doesn't have to pay so much? Any ideas on how he & I work out how much he should pay?

He got a promotion last year, and at the end of the financial year he's due to get a decent payment as a profit share with the company owners. If we split before then, would I be entitled to half of it as it's for his whole year's work?

Should I try to stay in our house (short term or long term), or leave & find a rental? Not working I doubt I'd be able to up the mortgage to buy him out anyway. If we were to sell the house, and I got a lump sum payment, will that affect my dbp payments? (I've heard it will).

Oh, and how have people managed to divide the house contents etc? I picture it turning into a huge argument. Is it safe to assume I'd get all the baby related stuff (he won't want much if any custody til she's older)https://9apps.ooo/
