Am I wrong for eating my pixie sticks different.

Before I get into the details I just want to clarify that I know it’s weird but that’s not the clarification I’m looking for. Now I (20M) recently starting talking to a girl in my class (F21). We both snack in class to help stay awake so we started alternating on days to bring snacks to class. This past class she brought pixie sticks because Sugar in a tube. Now here comes the part where I want to known if I’m wrong. I’ve always eaten my pixie sticks by biting and essentially breaking a piece off the stick and chewing the paper with the sugar. I don’t have a good reason I just do. Call it habit, so she saw this and at first didn’t say anything until I bit it again. At which point she told me that’s weird and I should stop. I laughed it off and didn’t say anything. Admittedly I could have probably not laughed but oh well. She then said “I’m serious stop that’s weird and if you don’t stop I’m not sharing any more” I’ll admit I could have stopped and been the bigger person. But a part of me is still immature and said “why should I, if you don’t like it just don’t look at me while I eat it”. She got mad and stood up and moved to another chair and the people in front of me said I should have just stopped since she asked. I just want to know was I in the wrong or did I make the right decision in holding my ground.

EDIT: after reading some comments I should clarify not that it makes much of a difference but I didn’t actually swallow the paper. I chew it then discard it after I’m done with the stick in the trash.
