What does it mean if you overhear the girl you like say to a friend that she is ok with the fact that you...?

I told two of her friends that I like her. she ignored me the next time we had school. Then the next two days we talked and everything was fine. She was coming down the row to sit next to me in homeroom like she always does and I saw a girl that I was pretty sure was told that I like her. I heard the girl I like almost seemingly yelling at her...."I know he does but im ok with it." or it was and im ok with it. could be about me but could not just curious what you think "I know he does but im ok with it means.
