Left my headlights on, but car battery didn't die… Will it die soon?

I left my headlights on while the car was off for about 30 minutes. The car still turned on, I took a 10 minute drive, and turned it off then on again just to see if it still works, and it worked.
It's a 2012 Honda Civic, and it once died about a year ago when I left the headlights on for 20 minutes then I had to jump it. So I'm worried that my battery DIDN'T die this time, because I don't want it to randomly die on me sometime tomorrow.
Will my battery die soon, and what should I do? Thank you!
