here- my girlfriend broke my heart.?

i have this girlfriend or let's say ex. we've been together for 2 and half years. her birthday was on august 24th, she spent the whole day and night with me. we went to the hotel and spent it there. at that time i was really happy and confident that she loves me still. she celebrated her birthday on wednesday august 26. she invited her workmates and friends, but not including me coz her mom against us. i was waiting for her outside of their apartment, she never answered my call and txt.she called me once and said she couldnt get out coz she has lots of visitors. i was waiting for her outside since 9pm-12mid. and expecting her to come, but she didnt. i kept on calling and texting but no reply or if she did she just said she cant come. so i sent some of her naked pictures to her workmate who was also there, coz i was really mad at her, i was thinking like how could she be happy on her party knowing that i was outside waiting for her. i was really hurt. i only forwarded her pix to the person that i could trust she would never send it to everyone. and then she got mad at me after that, she wasnt asnwering my call and text anymore. now its been almost 3 weeks, i could feel that shes really gone. she told me she's dating with her workmate which is a guy and his courting her. and she even told me she started to like him. and i could feel that too. i asked her why, hes not that good looking guy. honestly he doesnt look good, and his face is like an old man but he's 23 and he's very thin. but she said she likes him bcoz he's a good person. til now she rarely answer my text and call. everytime we meet i always cry infront of her begging her to come back. but she doesnt wnat me anymore. and since the other day we've been friends, she talked to me and cry. she said shes hurt coz the guy didnt send her a text message for 5days now and never came to her house anymore. coz before he always come and visit her, and now she said he has changed. and she told me she'll ignore him if she see hime at work, coz they're workmates. but this guy only work mon-tue 4pm-9pm coz he's in college and sat-sun same time. now i told her to stop liking him, coz he doesnt desever her, he will only hurt her. but whatever i'll say she wont come back to me. she told its over, she doesnt like me anymore and she doesnt want me to expect on her. im really desperate to win her back, and i told her i dont understand how could she forget me over to that guy. he's flirting her since august yet. we've been together for couple of years then now shes doing this.she said she just want to live a normal life, she wants to have a kids someday. i was like i know i couldnt give u that but u could expect me to love u forever. but really, for now i loss hope, its very hopeless, i dont know if i could get her back.pls help or IM me.thank u
