[P] How much data is required for making a model text like me?

Hey everyone,

I recently got this idea of training a model to text like me so that my girlfriend would not feel lonely even when I'm working or doing other stuff. I'm training it on the entire chat between me and her, which is roughly 200k messages, do you think this is enough for getting the model to act like me?

I'm very new to machine learning btw!
