I am married but have been separated for over a year. I have 5 kids that lived with me the whole year. Can I file HoH if I used unofficial spousal support to pay bills?

I only earned $3000 independantly, and I used unofficial support my husband gave me to pay all the bills for our household. In other words, I physically budgeted that support and paid the bills with it. Can I file Head of Household since my children lived with me the entire time, never staying with him, even though I didn't independantly earn the money to pay the bills?
