complicated....something which is sort of a compulsion-repulsion...need help urgently.

umm...it is REALLY complicated.....let me start from the fact that before i was this naive , nimble girl who believed in stupidly idealistic fairy tales and happily ever afters..until the one i thought would be my prince charming turned out to be just an idiot covered in tin-can foil....basically , he emotionally used me and i was nothing but a bet to his friends for him..he led me on to show his friends that even idealistic , moralistic , principled girls like me can fall for his trap...and it smacked everything i stood for and wounded my dignity when i realized i proved him right..after that i swore on God that i would not let any guy ever emotionally over rule me again...no matter what happens . Then arrived the most overtly proud , flamboyant , flirtatious lech i had ever encountered in my life...the moment he stepped into my school...all the girls swayed over the moon by the sight of him...i had this sort of tremor of bad vibes the minute i saw him lecherously checking out girls all around...it reminded me of my previous mistake...but when i felt that negative vibe, this time i was more strong ,conscious and alert of my states of mind...i was calm and felt self redeemed....one day , the flirt and so-called "god" which he thinks himself to be came to me with his fake stereotypical sunshiny smile saying hi to me and asking my name...i had a pretty tough day going on so i rudely replied "why? do i know you?".....from that day onward ...he kept on trying to communicate..to get through my mask of a rude ,overtly proud girl...but i did not let him..i was civil with him...but made sure that he knew i am not the sort of girls he hits on or treats like a bus , or i would not hesitate to slap him publicly...then , lots of unsaid things happened..i coincidentally laughed on a public class joke he made..and then he tried to make conversation..i was the same..civil yet dangerous..that's the girl i have become..... then a lot of one sided eye contact occurred from him...my friend told me the day i was not there for literature...even though he did not know me he had this very inexplicable essence of care about where i was and even stood up to look for me...which he even did for his female friend before , but apparently for me , the sort of care was different...something which neither my flirty friend could explain nor did i understand...and this friend i am talking about..she is the compete opposite of me...she used to flirt with him all the time and he being the guy he is did not discourage it..my friend finally went on to a steady relationship..and those singular eye contacts started increasing..i accidentally met his eyes just once...then again one day i was late to class..and he asked my friend where i was after looking around the room for 5 mins after he arrived...on a celebration in our school..where i had to wear a saree.....he stared so much as if it was everyone talking around him and him just gazing upon me..i felt the gaze..then he even used to not mind flirting with my friend if she did a bit through text messages .......i found it really confusing........one day , he casually told my flirty friend to give him a hug..he was dirty and sweaty...she enjoyed the attention..i rolled my eyes..cause i did not want her to flirt with someone when she is in a committed relationship and her boyfriend loves her like anything....so i looked away...the minute i did so..apparently his wide , flamboyant "i -am -all- the -shizz" grin..turned into a half smile..staring at me for about 10 - 15 seconds.....i don't know why.....somewhere inside i know his pride is a defense mechanism...but i also know that once a flamboyant over proud loser..always one...many of my friends told me that he had respect for me and i was different for him than other girls and he actually had something for me..i threw all my friends' analysis and depiction about this in the trash..but hoped that someday somebody will make him a better person...later on after 2-3 months those daily eye gazes stopped and he started gazing at my friend sometimes..and i had sense of remorse about it...i still don't know why......then after many , many days..just this last week...i was engrossed and happy in a conversation with my male friend..laughing away..as he was walking across...his gaze was completely FIXED AT ME....when he came closer to take the route in class he looked at me with an expression that i could not read...then as my male friend and i continued laughing...i got up imitating someone..and then saw him not gone..but standing outside the classroom door watching us two...especially me....it was so weird..then when i got to get my bag ...an anonymous bag was put right in front of mine literally hugging it..i got pissed and threw the bag lightly across another chair....his facial expression was first of like who the heck threw my bag?!?! then the minute he realized it was me...he suddenly had this down-to -earth smile on his face and shook his head and mumbled my name ... as if nothing happened and it wasn't a big deal..and then i realized that the bag is his...but the fact is he knew my bag.....he even gave it to me once when i went missing for class...then why would keep his bag in front of my bag..knowing it was mine all along....it doesn't make any sense........and then yesterday ...he was looking at the same friend of mine who gives him attention as she was singing and retardedly putting a hoodie on herself acting spazzy dancing around ...i just don't understand...any of it...i am sick of it..sometimes i get vibes that he likes my flirty friend..but all my friends around me keep telling me that i cannot see what is right in front of me..i ask all of you..now that i have said everything in details...is it true?can I seriously not see what is happening in front of me......help , please?.....PS- he had a disgusting habit before at least to lecherously look at every girls' chest..like i said ..he is a disgusting , conceited playboy..but even that time..i was the only girl he never looked inappropriately over there...he looked at me in the eye every time trying to say something that i never understood and still don't.....need advise urgently.
