There's this girl that i've been gaming she's giving me lots of IOI before, last week we see each other unexpectedly on a bus stop, I wrapped my hands around her shoulder and I said. How long have you been here? She gave me a short answer. She's not with her best friend this time I could tell that she's nervous haha! she has no back-up

I was teasing her, but she only says a few words, I got bored so I let her hop on the bus first I said take care I think she nodded dunno, i forgot. I felt that she showed me an IOD during that interaction so my gameplan is to ignore her next time I would see her. Yesterday! luckily I saw her again at the cafeteria sitting with her best friend, I was with my friends, we had eye contact she and her friend smiled and I heard her saying to her friend "wow! he's got a new haircut". but I ignored her, Me and my friends sat on a table where she would not see us! but then I noticed she and her friend changed location to where I could see her! she must be expecting that I would approach her! but I ignored her again. Going home on the bus stop! I did not expect to see her there again, she was with her best friend, while walking I saw her we had an eye contact but I look away and ignored her again. I said to my friend, hehe part of the gameplan LOL. Then I hopped on the bus. When I got home! I realized wtf! did I do the wrong thing?
Did I?
