send help

So around a week ago, my girlfriend spontaneously decided to add the letter "U" at the end around half of her words, justU like thisU.
Neither of us had ever said anything about it, yet I followed doing something similar by typing "uwu" at the end of every sentence. It was an unspoken rule.
Out of nowhere, she decides to stop doing it, and I am alarmed. Should I be worried? Is there something wrong? Should I mention it? Should I ask if there's something wrong? Why did she stop? Should I keep adding "uwu" to the end of all my sentences? Should I stop?

i'm a well adjusted member of society i swear
