Can I please get some help? :)

I am a 21 year old guy (turning 22 next feb) in college.
There was a girl back when I was in the first year of my college who proposed me.
She was 2 years older than me. But still , I accepted the offer because she seemed pretty cool and Honest.
,
I didnt wanna go into a relationship because of my family's financial situation. Heck , I could never even dream that a girl would want to be with me. But here she was , proposing me , flirting me. I , being in a harsh condition , felt pretty good when she used to talk to me. She used to pamper me , encourage me and everything. She was always trying to guide me in study related factors as she was 1 year senior to me in academic life.
,
After I got the chance in an engineering college , I finally accepted the offer. Things were pretty smooth.
1 month had passed.
,
One day , I asked her what she was doing and she replied in vague manner. Later , I texted her to give me a knock on fb when she is not busy with her fnds . She said ok.
At night , when she still didnt knock me , I knocked her. I said - whats wrong , why are you not talking? She said she was not busy anymore. I can talk now. Actually i wanted to give her the news of my first income (through tution) . She was not replying well. I asked her what she was doing , this time she went furious. She said it was a fnd of her from high school. Male fnd.
I said - but you said you never had male fnds!
after a while , she insulted me saying those guys are way better and more cool than me. She said I was a looser .
I was struck. I lost my mind. Said many things to her.
She blocked me of fb.
Long story short , I (!) appologized to her. She was okay with it after a few days.
,
,
She started insulting me by comparing me to another guy a couple of months later.
As i did not have a working father , my family was in a pretty harsh condition. I couldnt do things for her that a typical bf would do. But I was madly into her.
She started chatting and going out with a guy from her college. Again , when i interrupted , she stopped it but insulted me in return.
,
This continued for a while. We went out for long walks a couple of times. She never showed anything except love when we were together. I started to think she was really really into me.
I believed , as she said , that I was her first love. She said she had a few male fnds (now she is admitting it) and they were just fb fnds.
,
,
After a while , 6-7 months later , she was ignoring me. I , being so shameless 19 year old , still thought she loved me. She refused to give me her pics , said she was shy. But I found out she gave her selfies to pretty much every guy in her class who asked for it!!!!
When I confronted her , she said she was sorry.
i broke up with her.
But later she said she would do anything say but I must not leave her. I stopped calling her , texting her. But she called me like 50-60 times a day . So again , I was back with her . My fnds told me that this girl really loves me. I believed them and returned to her.
,
After a few months , she said she likes this another guy from her class. This guy was 6 feet tall with fair skin (In our country thats a H U G E thing) . This guy had a perfect score in the academics . Like the perfect guy. This guy proposed her. Gave gifts to her. My gf was pretty cute and hot. They started chatting on fb. But whenever i logged into her id , She would delete the message thread instantly. (like , in a flash!) She used to talk about this guy , how handsome he was and how generous he always was to her.
,
It hurt. Like , really hurt!
I forbade her to talk to him. But She did it anyway via a fake ID. This guy stopped responding to her after a few weeks when he found out that I (a bf that he thought was a rumor) really existed.
,
Her few classmates made threats to me that If I go to her college , they would beat me up . So out of fear , I never went there to confront them. These classmates wanted her to be in a relationship within the class (I dunno why , they would beat me up but would be happy to see that 6' guy with her) .
,
I was happy when that perfect guy stopped talking to her.
But this happiness lasted very short.
They were meeting and dating outside the classroom which I found out through a friend of mine from that college.
I tried to confront her. But she said - she wasnt interested in me anymore. In fact , she said she was not a relationship type girl . I was awstruck!
like , wtf! what are we doing then for the past 7-8 monrths???
,
,
She told me to stop texting her/calling her. She also told me that I WAS THE ONE AT FAULT!! I kissed her a couple of times , she said i was a perv . She said I was a porn addict (which I was not back then) . I watched porn but once or twice a month.
,
I again rebuked her with whatever slangs and everything....
She stopped talking to me totally.
A month later , I called her AGAIN.
I couldnt forget her , and I was also feeling guilty for rebuking her so much.
She said she really liked that guy , but she loved me.
A few days later , out conversations again became ALL ABOUT HIM!
This time , I called her a Ho'e , a bitch , a slut . I even called her an orgasmic nympho with nothing but sex in the mind.
,
After all this , 1 year later (last year) when I tried to contact her , she said she got married. I dunno why but I broke apart. I really thought she loved me.
Then , she sent a big bag of gifts for me through a fnd of mine .
I didnt even touch the bag. I was feeling that If I touch that bag , I would return to the point where I was in the beginning. I left it on the road side. After a few hours , I rushed to that spot (i dunno why) to take the bag. But there was nothing.
,
My fnd said there was also a letter in the bag written by her. I asked him where it was. He said the letter was inside the bag. So , the letter was lost with the bag.

,
Now , 2 years have gone. I still find myself stalking her on fb. She has blocked me , changed her number and done everything to get rid of me.
And I feel like a piece of garbage.
,
I need to get over her. I want to forget her like a bad dream. I want to prosper in life.
I try to stay busy all day . But what happens when I go to bed???
I never had sex with her . But still she is in my mind whenever I am trying to relax.
Its been a hell. She is in here when I am in the exam hall , She is in my head even when I am taking a poo.
I have recently found out that she didnt get married but is with that perfect guy now.
,
I need help.
I know I was a bi'ch back then. I should've left her at the first moment of dis honesty. But I couldnt do that. I still think I love her.
Can anyone give me a way to recover??
Time does not help. No , time recovers no wound. Thats a purely shit thing to say.
Note: She is a pretty rich family's girl. Her father is a powerful govt official. She is beautiful and near perfect.
I wanna know , How do i get over her??? How do I hold myself together?? I havent dated any girl since then. Every girl that I think of getting close to , feels like her.
It seems every girl on the planet will surely leave me for some perfect dude one day. I need help.
Can someone please help?

 

Stop stalking her on Facebook. Maybe you could get a job abroad.

 

I will graduate at 23

 

Can you study overseas? You can at the very least block her on social media.

 

I know only one piece of advice man... If you love her... Let her go!

How do I know? Cause I have been there.

 

She has told my friends that I was the one actually disturbing her. She even texted my sister saying that she will file a case against me if I keep telling her friends about what she has done (yes , i did try to reach out to her friends but none of them actually ever heard of me ) . She told me that her fnds know about me. But when I went on to contact them , they said they never heard of me .
