What; Do you think what Pain and I did was wrong?

I was in the 7th grade and I was going out with a 8th grader.And my 2 friends (I hate them,their some ghetto azz slts)where flirting with him.And he was cheating on me for like a whole month.I was in denile because he was my FIRST real boyfriend.And he dumed me like 2 weeks later.it was insutling and embarrassing,I was picked on and laughed at, in other words 7th grade sucked balls.(im in 8th grade now I love it) But my best friend Pain(14) and I(13) went to the park and we saw Korey(14) and he tought we were dating.It was soo fuk’n funny he came up to me and asked to get back together.But before I could say anything Pain had picked me up and threw me over his sholuder(I was mad because I had on a skirt and my Family Guy panties where showing) and walked away he was grabing my azz the whole time.All of his(korey’s) friends were around so it was even worse for him. You should have saw his face PRICELESS!!! I keep fighting with my brain because some days I feel bad for what we did and then some days I think I just don’t give a Sht he lied and hurt me.Pain and Korey are in the same school&grade and I’ll be going to the same high school next year and I’m scared Korey ALL ways gets back at people he did it in middle school all the time!!!He has this ego where he think he’s king and if you ask most kid that know him they WIll 99.1% of the time that his full of sht and doesn’t care about about anyone.And example of this is:I broke my ankle all my friends called BUT HIM MY “GREAT” BOYFRIEND. Pain also thinks he has to “protect”me because im to “native”,too nice,and small.(im 5’2 and 105 with a hot body so be jealous LOL)But I just don’t want this to bite me in the azz when I go to high school.
