Can my parents sue me for money that they gave me over the years (largest amount was for college tuition) if I am married?

I have been trying to do research but I thought I would post here instead, and get some real people's opinion. <br><br>My parents have always been good about giving me monetary gifts (I am the only child) and giving me money for school, for my first car, living expenses, a down payment for a house, etc. <br><br>I was thinking about the money I received from them when I was in college. I had a full ride scholarship, but they gave me money every now and then to help with summer classes, books, any random expenses, etc. Or they would pay for a trip for me to go visit them, or they would pay for me to fly home sometimes. <br><br>My partner and I are discussing marriage. I don't think my parents would willingly ask me for money, but in the event of a divorce, can my parents sue me for all the money they gave me? Would I have to pay them back? <br><br>tl;dr: over the years parents have given me a decent amount of money, does this mean they can sue me in the future for the money back?
