Why do I feel upset that I spoke to this girl before she approached me ?? Why do I feel this way ? Should I just ignore her again ?

I am a guy 21 years old. I had a fight with a female friend in which she told me that I am very very irritating and this hurt me a lot for some reason. I had completely ignored her for 2 weeks during which she did look at me many times . But today for some weird reason I went a spoke to her . I feel that if she was a real friend she would have definitely come and spoken to me but she didn't . I realised this after I approached her. Now my ego feels hurt. What do I do ??
