Why does my girlfriend (34) do this?

it happens every so often with small what I would call trivial things. These small criticisms are like a small stone slowly grinding away our relationship.

Yesterday I sent a morning text "morning baby, Have a lovely day! 🥰'

Today i send a morning text "morning have a wonderful day!"

She replies to yesterdays message with "see the difference from yesterday to today in your own message?"

Yes I did not include the word baby or an emoji but it was not done on purpose. I text with and without emojis to her all the time. Sometimes I am in more of a rush to get to work or simply forget. If she does the same thing I don't even acknowledge it because I know there is a perfectly logical reason behind it. It isn't just here either, if i dont text back quickly enough I might receive a "you don't love me text 😢", in face to face conversations if i dont respond or display emotion in the exact way she wants it (eg excitement - if i am not bouncing off the walls excited) then it shows I don't care enough.

I am starting to feel like I can't do anything right, that I am becoming vigilant to my own behaviour so as to try and not set her off.

What do I do?
