I know this is difficult for you to comprehend but I was done with my sentences! That's why i had the explanation points and the emojis at the end! :)
I don't think you said what you meant to say. Having "exclamation", not explanation, points doesn't make it not a sentence.
Or if you were trying to say that you were done responding, then you should have just said that, even though that wouldn't be true either since you kept responding to him.
So you're really just not making sense at all.
