Help ME!

Ok, so this really cute guy, (my crush) asked me out a few weeks ago and I said yes.
Then I broke up with him the next day.
At the treat cart at lunch I was sitting with my friend, Noah and I think he was jealous because he went there like, 15 TIMES!! He was totally jealous.
And now he still has a crush on me and I want it to stop!!!
HELPP!!!
