I'm married for 10 years. Live in FL. My husband is not my child's bio father, only step, never adopted. If we get divorced, will my child be entitled for a child support?

I have 2 children from another marriage. They both live with there stepdad and half brother. My 2 oldest are 19 and 17 can he get child support from me because they choose to live with him.
