What Should I Do about this guy ? Please help !?

Im sorry this is really long, but please bare with me, and try to help.. Please, I really need it...Kso, I have had a crush on this guy since Grade 2, Started out as a childish crush, but got stronger about 2 years ago. He told me 7 months ago he liked me, at our Band Concert . Right when we where playing. I was in shock. Then after i talked to him about it and he said he had liked me for awhile.. i couldn't believe it ! seeming the year before, when he got out of a relationship, His friend tryed helping and said hey, theres plenty of fish in the sea, and asked him what about me. and he told him he would rather die then go out with me.. Ouch.. I didn't want to date at the time, seeming i felt like this was a Dream, 2 months after that was our High School Dance. When the slow song came on, he asked me to Dance, i had never danced with a guy before.. But i did it, and it was about the best night of my life.. 3 months after he asked me out.. I said Yes, we went out for a month, but we didn't do anything ! It took him 4 weeks just to hold my hand, every other relationship he has kissed the girl by the second week . But he never kissed me.. he would always say he wanted to but never did.. And i was way to shy to make the first move, he was my first relationship.. He asked me out 3 weeks after the breakup, but only went out with me for a day, told me it was a mistake to ask me out again, that i have changed.. even one of my best friends told me i have changed ! But i want to change back if its gonna get me the guy i love back, and my best friend ! Anyways.. The only thing on my mind lately is how can i get him back, whats going on in his head ? If i kiss him, will he reject me ? I really really want to kiss him, just so i can finally get it out of my head, and i want him to be my first kiss.. Can someone please PLEASE tell me what i can do about this guy ! All i want is him back, but i feel like im too late ...
