She looks younger than 27. Plus, my spidey senses are telling me this is either a bot or a Nigerian prince running the account.
Assuming she isn't OP is missing opportunities here.
When a chick texts "hehe" which is an invitation to flirt you shouldn't respond with "I'm washing the dishes", when she says you are a "diligent man" you don't say how lazy you are unless it's very clear sarcasm.
And when they tell you they watched something called "teach you a lesson" you take the opportunity with saying you're going to "teach her a lesson" and then take it back with plausible deniability (i.e., make it something innocuous when she's starting to think you may be taking things somewhat sexual).
OP spice things up now or she will lose interest quick. Even if she's a "good girl" you can't be boring.
