Is it normal to stick on to your ex

there is this guy,i never knew he existed for a year and this sudden day in class he happens to sit next to me, surprisisng because i was supposed to be next to someone else.was getting bored so was facebooking,and then he starts annoying me that i am trying to show off with my fone,told him i wasnt but he kept going on about it.maybe it was a bet not too sure now and dont care.this went on and we both kept dissing each other,but i was attracted to that attitude he gave me..i dont take trash but his was different.he then asked me out and i said no,actually then i was looking at some other guy i knew.told him so, in a bad way, i thought he was trying to play my head so was mean, he just said he knew he wouldnt have gotten me that i was too good for him,i felt guilty and had to call him and apologise,had to get his number from some common pal!so uh yh then we used to talk quite abit..then i dropped off this other guy, not cause of this attitude guy but that other guy was thick and stupid.we talked and it was just talking ithought,silly things happened and we did annoy each other a few times but we fell in love slowly,and its love for me coz i have never felt this deep before,had once thought had fallen in love with some guy before but after i found out he had dropped out of school i felt nothing for him so it wasnt love, but this guy, nothing has changed what i feel for him, even the fact that we broke up because of me, he had stopped paying attention and since all my friends kept hinting that is how guys drop off chicks i din want him to do that to me, we like never talked, he used to ignore my calls, never replied to any text.but he still behaved okay and ofcourse am still in love, and he told me he loves me too,we still hardly talk,i have tried so hard to get back and somehow i ended up being too gluey, it was bad,i have never asked someone to be with me like this.but it was more important to get with him,but he dint return the efforts so i feel like such a stick on!he night be thinking the same,and that knowledge kills my ego. wouldnt deny i love him, and he did love me if not now at some point..i love him, i dont want to forger him he gave me the most genuine and happy momens of my life, i cant get back with him, am trying not to bother him or kill my own ego by asking him to get back again,how do i fight my own feelings that i had become such a gluey person??there is nothing to blame him about, we had no doubts insecurities, i dont know why i left him now, just because he didnt give me attnetion!!i want to just get that respect he had for me before and somehow forget that i could be that way too.plus need to rescue my self esteem and ego..i dont want to force a get back he made it clear that he doesnt want to .this is 8 months now that we broken up, my feelings for him i can deal with later, i want him to think of me as highly as used to before we broke up and i became like i never was
