How do I file

My husband lives in Texas and I recently (October) moved to Hawaii. What is the best way to file. He is retired military and receives retirement and 100% disability. He is currently unemployed but I work in Hawaii. The state taxes in Hawaii are very high and take out a big chunk of my income. Initially I put on my W2 married filing separately but changed it to married. Can I claim him as a dependent to reduce some of the Hawaii state tax. Or would that cause me to owe on my taxes when I do file. Can I also put myself as a dependent. I want to know what my best option is to be able to afford to live here and still not owe on my taxes.
