how i lost him

here is the story about how i lost the love of my life.
i started working at my job a year ago. at first, it was tough because i wasnt used to really socializing around. but after a week, i had managed to make a few friends. one of them was a guy that was short but very cute. he would always greet me with a smile and a warm “hello!”. for the next few months, he became one of my closest friends there. he gave me his number and we would stay up late at night having conversations about life and work and random things friends would talk about. i started to develop a crush on him, but i knew nothing would happen because he was older than me and in a relationship. a few months later, he broke up with his girlfriend of 3 years. he told me she wasnt his type anymore and he had feelings for someone else. thinking it was me, i tried everything to be perfect around him. but, i later learned, it was never me. i spent the next weeks upset and eventually, we stopped talking. i met a new guy and started dating him. he always made me happy, but never as happy as they guy from work made me. we broke up a month later because i found out he had another girl besides me. crushed, i called into work the next night because i was too upset. i had told my best friend everything that happened and as she tried to make me feel better, i had spilled to her my feeling for the other guy. she said she had an idea and hung up. the next night, i sat on the couch all night and cried over love movies. just as i was about to go to sleep, i got a call from the guy at work telling me he liked me. i couldnt believe it. so i jumped at it and told him i liked him too. but, he had already known. my friend went into work and told him everything i told her. though i was ticked at her, i was happy at the same time. for the next month, me and the guy at work went on dates and talked all day and all night. on one date, he even kissed me! i went and met his parents and one day, he bought me flowers and asked me to be his girlfriend. i freaked out with excitement. for the next 3 months, we had the best relationship i had ever been in. no fights, no problems, absolute bliss. one night after a date, he walked up to me and held my hands. he looked into my eyes and said the words no girl wants to here. “i cheated on you and i love you, but i cant do this anymore” he had cheated on me like my last boyfriend and just left me. now i am here, its been a month and my heart is broken. he still loves me, but he doesnt want me back. how am i supposed to move on from all of this?
