Probably not, given your living situation.. The IRS spells out the HoH advantages and requirements in Pub 504 (I've added emphasis on the 3rd bullet point to the "Considered unmarried" definition):
------------------------------------------------------------------------
Head of Household
Requirements.
You may be able to file as head of household if you meet all the following requirements.
-
You are unmarried or “considered unmarried” on the last day of the year.
-
You paid more than half the cost of keeping up a home for the year.
-
A “qualifying person” lived with you in the home for more than half the year (except for temporary absences, such as school). However, if the
“qualifying person” is your dependent parent, he or she doesn’t have to live with you. See
Special rule for parent
..., later, under Qualifying person.
Considered unmarried.
You are considered unmarried on the last
day of the tax year if you meet all the following tests.
- You file a separate return. A separate return includes a return claiming married filing separately, single, or head of household
filing status.
- You paid more than half the cost of keeping up your home for the tax year.
-
Your spouse didn’t live in your home during the last 6 months of the tax year. Your spouse is considered to live in your home
even if he or she is temporarily absent due to special circumstances. See
Temporary absences
..., later.
- Your home was the main home of your child, stepchild, or foster child for more than half the year. (See
Qualifying person
..., later, for rules applying to a child's birth, death, or temporary absence during the year.)
- You must be able to claim an exemption for the child. However, you meet this test if you can’t claim the exemption only because
the noncustodial parent can claim the child using the rule described later in
Special rule for divorced or s... under Exemptions for Dependents. The general rules for claiming an exemption for a dependent are shown in Table 3.
------------------------------------------------------------------------
The publication has further discussion and provides examples of various situations. You should probably read through this for a complete understanding of when you
can file HoH.
