Something strange just happened with my girlfriend. She is unicorn material and claims I took her virginity which is why I LTR'd her. She came over for a few minutes to hang out with me (we live across the hall in a dorm). She sat across from me in a cozy chair. I said, come over here so we can cuddle for a sec. Normally she's fine with this. However, this time she sighed like she was exasperated and said "I guess..." I then said, no, you don't have to, and proceeded to go back to what I was doing (reading), ignoring her, while she sat there in silence and read too for the next hour. She then asked me if she had done something wrong, because she sensed I was mad, and I said, "well, you basically rejected me when I tried to be affectionate a while ago." She then said, "I was just joking." I told her I wasn't convinced by that explanation and it was fine if she didn't want to cuddle at that moment, but please don't make shit up about "joking." She continued to maintain it was a joke and that "we joke like that all the time". At the end, she said "can i have a kiss," and I said, "no, because you rejected my affection earlier. Goodnight" She left and went to bed.

Did I fuck up here? was I in the right to be mad that she rejected me? She'll probably dump me now, right?
