I'm a new taker of the pill and have been slowly applying the teachings here to my life but feel like my text game is lacking. Last week I met this girl at uni, she's very much into me, the body language signs are very obvious etc. and got her number too. Anyway, she texted me yesterday about some kind of an important exam she apparently passed, and a conversation started as follows(and yes, I know about texting for logistics only, and I did steer the conversation that way):

Her: btw after each of my exams that I successfully pass, there's always someone who gives me chocolate, cakes, presents etc. see 😂😂

Her: That's why I'm a sweet little girl like this (she's 2 years older than me, joking about that)

Me: tbh I wasn't expecting you to be 25.(age negging)

Me: Hah! So should I believe you really passed >:)

Her: Yeah! I'm expecting x mistakes, I'll probably be xth

Me: Good girl

Me: Then to celebrate, YOU should buy me a breakfast at X place

Her: Riiight sweetie, you must've misunderstood, it's you who needs to buy me breakfast to celebrate ;)

Me: Poor you, you wanna get rewarded? ;)

Her: Yeah, I earned it :)

Me: Well you gotta try harder to earn my recognition

Her: Hmmm, I had no idea I was the kind to make effort to gain approval 🤔

Me: Me neither

Me: You surprise me 🙈 (clearly mocking her)

After which she didn't respond with anything and I haven't said anything either. I tease and mock her a lot because she's egocentric, always complimenting herself and trying to get my attention, she's a tease herself, and there's also no way I'm buying breakfast for a random HB5 I met a week ago who's ASKING for gifts. However for this instance I want to know if I have fucked up somewhere, why she has ghosted, did I have the right attitude, is there too much teasing, too much cold neg etc. because I am well aware my text game is very much lacking and I'd appreciate it if you more experienced TRP guys gave an insight and guidance so I can correct my mistakes. Thanks in advance.
