Should I just leave it ???

So it all started in p5 when I walked into my classroom in p5 at primary and there is a boy in a wheelchair named Brooklyn and a support staff beside him (miss cordiner or Eileen ) , a few weeks latter Eileen askes me to help out with Brooklyn so I said yes but I started hanging around with Eileen instead of my friend group but anayway since that day I have been by his side and Eileen and I are like best friends but as we are going into p7 Brooklyn - Brooklyn always askes me for help - when he asked me to show him something he turns away and talks to someone else also I now sit beside him and he calls me all sorts of names *wont go into detail * but I know it is prob just for a laugh what should I do ;

Tell Eileen that it’s too much or just leave it -ps I am 12!
