Context, i was having breakfast with some friends both male and female. I just woke up, so i was really relaxed and chill (in contrast to the last night where i was really energetic and "cocky").

The girl that i like was around, so after she sensed my relaxed behaviour and body language she came and sat next to me. I was really dissmissing her, showing desinterest and cutting my attention towards her because the night before she was "playing" hard to get. I cut the attention since i didn't want to play games.

So after she senses my relaxed behaviour and desinterest, she started to try to get my attention by iniciating conversations and leaning into me. I was complety dissmising her, acting like she didn't exist.

I was socializing with my other friends in the table. She was desperate to get my attention. So eventually i said a cocky/bragging comment saying something like "i'm am the best and i'm pretty egotistic person" but nothing that serious in a conversation with my buddies.

INMEDIATELY after i said it and she heard it, she stood up and WALKED AWAY from the room...

Minutes after, she left and went home and didn't even say goodbye to me.

What went wrong? Was that bad?

Important information: she is a girl with daddy issues, insecure, but definetly a 10. The night before i didn't have "luck" with her. She seemed disinterested, and i was in the other side of the spectrum of "energy", basically super energetic and sociable behaviour.

That morning in the breakfast, i was in a chill/relaxed mood due the sleepy mood, was only after she saw me in that "mood" that she became stupidly interested trying to get my attention.
