Things are going downhill between my girlfriend and I what to do?

My girlfriend and I haven't been talking for the whole week and when I tried to call or text her she doesn't respond. The story is my girlfriend and I are in our 20's and she still lives at home until she gets a better job to move out and she is in school. She wants me to come down to her house but I don't want to since she still lives home. We got into a big fight and it's a diaster now.
