Can i file head of household?

I am married, have been since 2006, but my husband has not lived with me for 8 months now, he has been living with his family in another state. I have worked and payed for all my rent and the care of our daughter. I dont want to file jointly since he owes back child support and i really got screwed out of my refund even after i filed the injured spouses form. So my question is will it be okay for me to file HOH?
