i am obsessed totally obsessed :( i dont know how to get over it?!

well it all started 4 years back when he came in my life . when i met him i had a feeling of enormous happiness . i was totally over whelmed by it . to me it was the best thing that ever ocurred to me in my life time . he seemed so beautiful so fun to me that i couldnt resist . i started going out with him . but then i realized that i was getting head over heels with him already in a few meetings and i was scared he might leave me . i could not imagine my life with out him . i can never explain the happiness that came to me with him . i just know that he said i will be the happiest man on this earth if he gets me . but i was scared i will loose myself totally i mean physically so i stopped seeing him . he called me after mobths and told me he was not happy with all this and he wants to se me again . i again tried but then i had to see him agin . this time he took me to his house and introduced me to his brother . he was so much hapoy and that was obvious . he wanted me to meet his mom as well some days later but i was not allowed by my mom . he too was madly in love with me . but i was swept off my feet when he told me that he hid something from me because he didnt want to loose me and i was the best thing that ever occured to him . the same was my feeling . he had to reveal that his family has already tied him to some other girl but he just feel like he was meant for me and was so happy and doidnt want to llose me so he hid this from me . i abused him a lot for the damage that was already done . i could not run out of love at that time . i stopped all contact with him . but i could not move on . every relation reminded me of him . i still was obsessed . the last time i was hooked up i could nt help crying and contacted him again . coz it was so enormous that i could not help it . he took a stand for me in front of his family but the girl he was engaged to was of the family . she threatened me that she is gonna kill me . or get acid on my face . i was not with him but the girls was threateing me a way too much . seemed she is gonna fight like abitch for this . he broke up with her and came to me all by him self and said he will make it possible by any how . mean while is was still getting threat calls . then he called me one day and said i am failing . i swear u are the love of my life . but it is a bug ditch and i just know i have to be there . but there is only one truth about me that i have only loved you . they decided to get him married and this is what he told me . but i have beenloving him for so long and i just know that he was the best thing taht ocurred to em . i still cant stop myself from thinking . no matter how much i try . i am still revolving around his thoughts . it was the happiest feeling for me and for him as well coz he said once that if we get together he will be the happiest man on this earth . i dont know what he is going through but i just know that soon enough i will be totally psychic . i cannot do any thing i want to do . i am just so much out of my self . i just dont know what to do . my world my love my life all is lost
