Why does she suddenly start using my name when talking to me?

So this girl I’ve been talking to recently started calling me by my name. Whether it’s over text or in person, she has been using my name all of a sudden. What could be the reason? Is she flirting or friend zoning me?

And on top of that, she has been saying Pat instead of Patrick, even though everyone calls me Patrick.
