Should I file as head of household, married filing separately or married filing jointly?

My husband and I are dual military and are stated at two completely different posts in two different states and no time during the year did we actually live together. I live in an apartment and he lives in military barracks. All of our money is kept separate and we have paid for any of each others things. We also has a baby in 2016. Would it be best to for me to file head of household because I fully support my daughter and my husband hasn't lived with us. Or can we only file married filing separately/jointly?
