Auto Insurance After Marriage

If I get married…?
I am in Texas.
I have medical insurance through my dad’s military benefits, will I lose that when I get married?
I have auto insurance through my parents, will I still be able to be on their insurance(the car is in my step-dad’s name)?
If I get married what are the other things I might need to think about.
(By the way, we have gone through marriage study before we do get married)
~When you get married you become your own person, responsible for all your affairs, including the ones you mentioned. No more daddy or mommy to carry you along…
