Can i file head of household if I am paying all the bills and have someone else living with me

Maybe----but that depends on who the "someone else" is.   You cannot use a GF or BF as a qualifying dependent in order to file as HOH. 

Am I Head of Household?

If you qualify as Head of Household, when you enter your marital status (single or married filing separately) into MyInfo, and then enter your qualifying dependent, TurboTax will offer HOH as your filing status.

If you do not have a blood relative as a dependent on your tax return you cannot file as Head of Household.  You will have to file as Single if you are not legally married.
