Don't know what i did wrong.....?

This girl at my gym and i cleared the air so to speak about things(in a non-verbal way).On fiday she came next to me and we started up a polite conversation.We had differences in the past(her being iranian and me being asian that bordered on racial)But over the past couple of times she has made it clear to get my attention.All i did was apoligize for things.On friday,it was cool,she was comfortable around me and we had a decentl polite friendly conversation.Today she sees me and leaves the gym.I've avoidede her too because i like her in a way,but i can't figure out why she woul do the same.Our past incidents were fairly harsh so i don't know if she's still harboring some hatred,but i've done my best to clear things up.What's the deal with her? If she doesn't like me,i can undersatnd and deal with that,but i did nothing wrong to her with the way i've comeacross.
