My crush called me dude

My crush and I were talking today, mostly one on one for a solid hour (probably longer I think)

In about the middle of the conversation she called me “dude”. It only happened once in the entire hour.

Does this mean I’ve been friendzoned?

The conversation went really well, back and forth, all kinds of topics and she seemed engaged throughout. Nothing particularly flirty per se but when I asked her if she had any plans next week (aka hinting at Valentine’s Day) she talked abt other things she was doing but nothing abt the 14th.

Idk is she interested in me? It’s so hard to tell
