pffff:))) another "advice" problem over here:/:/please...help:)

lay back and sit comfortable...I know this kind of アドバイス problem is being repeated and I was sometimes answering them but ...I tried and I cant give アドバイス to myself:)) I dont know what to.."think",precisely.
umm let me start with the 質問 :
what does it mean?
...
So, this year,Im in yr9.... I went to a new school and came in the same time with a new guy: "Markos".
at first I didnt even think about him but then I had a really weird dream with us hugging and kissing.
the problem is...his just the really bad-guy:)))
the smoker and druggy guy who get's into the principal's office quite alot.
in lesson's I caught him staring a couple of times and now it's just akward...
1.the staring
2.the smiling
3.the...akwardness when we stay 次 to eachother.
it's obvious I kinda..fell for him and my フレンズ say we two match...pff:)))
ummm...but 2 days 前
he コメントしました something..which I didnt quite understand I thought he was somewhat saying something bad...
and I said: "Markos its not your business<.< または something like that (as I 発言しました it in my language)
and...I was expecting him to start swearing like guys usually do but he just looked at me while I looked at him...nasty
my friend started shouting at me as she thinks he 発言しました it as" defending me"(the subject doesnt matter it was a conv. with a teacher about a mark)
and the staring continued...

I thought of giving リスペクト for help but wouldnt that be "forced help"
I mean if someone wants to give me an アドバイス he/she shouldnt expect something back...right?:)
so...whoever has the patience to read this please help me:)
