My husband and I separated a year ago. He left me with no money and I am disabled; can I seek immediate support?

We married and lived in CA. When we separated, he walked out and left me, disabled, to clear out the home we rented. My mom had to fly out from Maine to help me and since he left me broke, I had to move back to Maine to live with my folks, who are struggling themselves, financially and with health. Two months after I left CA, he left a great job and moved to TX. After 6 months in Maine, my folks decided for all of our health, to move to FL. He cancelled my health insurance 3 months after we separated, leaving me unable to get the medications I need. This has caused my disease to rapidly progress and the damage is irreversible. He also stopped paying for the vehicle I drove and the insurance, without telling me, so I was driving it for months, unregistered and uninsured. He threatened me about many things and said if a judge orders him to pay me anything, he will disappear, which is why I've held off seeking spousal support. But, because of that, I have struggled beyond words this past year. I can't do it any longer. My father recently suffered a heart attack so now we are even more in the hole. I know my ex makes very good money and doesn’t have much debt. Our whole marriage revolved around him, his career, his education, and paying his bills, so he has excellent credit and I never did anything for me, to better my life. He was verbally abusive. I am too embarrassed to say how he treated me after having both my knees replaced. So, my question is, now that I've met the 6 month residency requirement for FL, can I seek immediate spousal support until I’m able to file for divorce?
