I want him back...10points?

Im in. 8th grade. Sorry about typos I'm on my iPod. Anyways this boy asked me out on Tuesday and I said yes and on Wednesday I broke up with him.:( I'm so stupid. Do you think if I sent him a message/ wrote him a note saying, " I made such a bug mistake when I broke up with you, I would love a second chance. I promise I won't let you down." or something like that he would take me back. He really likes me , I think. Judging by his reactions to the breakup.
