In order to file as Head of Household while married, you must meet the following requirements.
File your taxes separately from your spouse
Pay more than half of the household expenses
Not have lived with your spouse for the last 6 months of the year
Provide the principal home of a qualifying dependent
Claim said dependent on your tax return
If you cannot meet all the requirements, I suggest you either file as Married Filing Separate or file a Joint return with Form 8379 to be considered an injured spouse.
