Is it normal to have these feelings for my first love?

hi friends im gonna share my feelings about my first love
i proposed to a girl in my 7 standard actually she was from other school she was so beautiful,pretty,smart n well read
but she refused it n she didnt talk to me for 2 years then at 10 we begun to talk by that time i realised its just an attraction even she forgive me for my inconvenience later we went to different college for the pre university course i enjoyed a lot in PUC with my friend/girlfriends i couldnt score well but she did well after PU i went for engineering
she went for BSC even in engineering i couldnt do well i used to flirt girls in phone by calling them at mid nights with unknown name n with a new contact no this became my hobby somehow i was able to get her no from my school friend so i tried the same with her to know weather she has changed or not u know girls get change as they mature so i tried it but she dindt change even a bit she was the same as in school days i always wanted a girl like her in my life. but some how she came to know that it was me who was calling to her then she was very much upset about me she never thought i would like this later then i stopped doing such mischieves not only with her with everybody after few days she changed her no then one day i got a message from an unknown number it was her saying that "how are you sunil this is ******"
i got shocked later we began to chart meanwhile she came to know everything about my character,hobbies,love,studies,everything i had said her that i doesnt have a girlfriend she asked me that "will you
marry me" i didnt know what to tell because i never expected this the girl whom i loved in schooldays n got refused from her will ask me like this i just asked her "do u love me" she said i dont believe in love i wanna marry u but i always wanted to hear her saying "i love u" so i tried to convince her to love me even she understood my feelings she committed to love me we were in good relationship for a long time even we committed to get married after 5 years since now she had said that there wont be any kind of trouble from my side im all set clear my parents will definitely agree my dicision but i was scared about my family wheather they will agree my decision or what like that but she was so much clear in marrying me but suddenly i dont know what happened she stared avoiding me refused to meet me,refused to accept my new year gifts later then she said that "i cannot marry you my parents are forcing me to marry my relative guy if not my mom will not live" like that it hurts me a lot the girl of my dream is ready to marry other guy i cant digest this feeling im really confused now wheather she forgot my memories,our meeting, our phone chats everything im really fucked up now im on my way to forget her i know its not that easy but as time passes it keeps me away from her memories but i always wish her to be happy with the guy whomever she marry but nobody can love the way i love her.............
