20M,19F: She gets upset when things don't go her way. I'm feeling trapped and don't know what to do, any tips?

My girlfriend gets upset when things don't go her way. She says everything is fine but proceeds to do something that she knows for a fact irritates me --- which will lead me to ask her again and again what's wrong then ends up me "pushing" that something is wrong, where clearly there is like: she just becomes suddenly cold, her language becomes more mean or just plainly ignores me. Currently she's upset because i won't drive her somewhere, which is unusually far (not to mention i have to pick her up first), she knows how far the place is and how long i have to drive just to get to her. We even have conversations about me not wanting to go out as often because it tires me out personally and I would like to just hang out at home for a while -- but then she does this. She's apparently going out with friends whom i have never seen in my life and then going to the place she mentioned. I dont want to open up to her about this right now because it will spiral into another fight. I really feel stuck atm.
