Seeing My GF for the First Time Since our First Fight

We had a fight on Monday. I unintentionally made a thoughtless remark and she was furious. I immediately apologized, but we had to part without things being settled. We were apart for Christmas Eve and Christmas Day. We texted some and she said we are fine, but I can't help not being nervous. We've been together 7 months and only had a couple of minor disagreements. This time, she flipped out. It's been ruminating in my head the whole time. Every scenario I could think of. She says we're OK, but OK doesn't necessarily mean good. She hasn't expressed forgiveness. I'm uncertain and nervous. I haven't slept much since. I don't know that I need anything from this group. I just needed to get this out to people who I know would understand. Thanks
