AITA for meowing constantly at my gf

I (18f) and my gf (18f) have been dating for three years. I have always meowed at people like my family and friends. I just meow. When the conversation is getting boring: I meow. Whenever its quiet: I meow. Whenever I just feel like it : I meow.

My girlfriend over the past year has been telling me that my meowing has been stressing her out. Once every couple of months, she lets me know while I am meowing that it is stressing her out. I dont know what to do, its like a part of me. She says its not annoying its just like making her stressed and stuff.
