A year ago sth bad happened to me & for 3 months i was really down,then i got better,but it still hurts,help?

ok,here's the thing,I am a religious person & there's this boy in my university that he's actually religious,too.in our cl ,i'm the best student & he is second best,& we have all these things in common like we r both movie freaks,& ofcourse have the same ethical way of thinking,there is this other religious girl in our cl & she has the same way of thinking,too;but she's is one of those that is so obedient & would never disagree with her partner,& she's an average student,but she's hotter than me,not that i am that disgusting or she's a 10,but she's hotter.a year ago(God i can't believe it has already been a year)we had this course with this pig headed stupid teacher that wouldn't let us be apsent one session before the holidays,& i had a french exam in that week & didn't have the time to come,so i suggested that none of the students go to cl that day.but then i remembered that i had used all of my opportunities to be absent & thee teacher could easily fail me if i had one more,i freaked out & decided to go but i informed all the other students,so i wouldn't have betrayed them.but only me & 2 other students came that day,& after the holidays eventhough the teacher didn't consider any negative points for them,they all ganged up on me,now after one year things r better,the students aren't that hostile anymore,but i really don't have a ny close friends & the worst thing that could happen ,actually did happen,the boy i liked ,married the other girl,i'm not saying that i loved him,i just can't stand the feeling of being rejected,& the possibility that I could never find any one that is as close a match as he was to me,u know he isn't even flawless,like he wants his wife to obbey him unconditionally,there was this exam that was unfairly difficult & because he couldn't get a good mark he erased all his answers as objection & suggested that whoever is brave enough shoud do this,ofcourse no one except him & his wife did it,& it wasn't even brave,it was rude & stupid,so just the 2 of them failed that course & I got A+,& generally i feel that he is jealous of me getting higher marks than him,& i think one of the reasons he didn't choose me was me being much a better student than him,I tried to get transfered to another brach of the university,but they didn't let me.i can't stop comparing the girl with myself & feeling she's much better than me,eventhough deep down,i know that's not true.i just can't stand seeing them together,& when i talk to my mother about this,she feels sorrier than me that i lost him!it hurts so much,i just need some advice to know how to deal with this,how to not let it get to me anymore.thanx
