Ok, I'm not even sure I'm supposed to be posting in this place, I dont care if you delete this topic--but I really need some answers.

Ok, first of all, since my problem is about a girl, I figured GIRLS would be most helpful, seeing as most guys are absolutely dee-dee-dee when it comes to relationships.
Ok, so to the point.
I met my ex girlfriend in 6th grade, she moved away, I continued living there for a few years, then I met her again in 8th grade.
We started going out. I realize theres alot of people arguing that 15 year old's dont know what love is, but whatever--THAT, that was love. No f**king doubt in my mind.
I fell completely for her. Absolutely and totally devoted to this one girl.
She was perfect to me, abso-f**king-lutely perfect. A few months in, I thought it would make her happy to give her a ring for our 6th month anniversary.
So, I got a job, babysat, mowed the lawn, in short, I broke my goddamn back and managed to get around 750 dollars. I went to a jewlerers, and got her the prettiest ring I could get her with 750 dollars, then I gave it to her. I like, kinda proposed half jokingly to her, like "Danielle, would you marry me?"
But then I saw her reaction, and I was actually shocked.
So we were engaged.
I bought her a necklace sometime later, (which wasn't cheap by the way)
Months passed by filled with so much love and happiness I probaly should have died then, cause I don't think I can experience uplifting joy like that ever again.
I wrote her poems every single week. Everytime we met I kissed her on the cheek.

Sex wasn't even on my mind, cuddling was enough for me.
We were perfect.
I loved her.
She loved me.
Then I found out, the day before my birthday and a few days before our one year anniversary, that she's been cheating on my, the.WHOLE.damn.time.
She's had sex with two other guys, and was messing around with a few others.
I won't delve into all the melodramatic weeks that followed, but to say the least, my world fell apart, cried for days on end, and so on.
Now, I come here, just wanting to know, was there anything I did wrong?
I mean, If I could I'd have given the world to this girl, and I tried.
I didn't even look at a girl twice for nearly a year, she was my life.

So...yeah, thats pretty much it.
And all I want to know, if theres ANYTHING you think I could've did better, or something I did wrong.
I'm just looking for answers.

-Sorry for being so long...and thanks to anyone who helps.

Then, I found out

im going to tell you what i told my friend anthony... he had been dating his girl friend for a very long time (four years) and also talked about marraige. When he found out his girl had been in another relationship he was completly devastated... Even i can relate to you, i ahd a girl friend that i spent lots of time and money on... i dated her for 1 and 1/2 years and she cheated on me too... i was devastated, and i dont want you to go through the same sh*t as i did.

helping yourself get over it: Talk with someone about it. Tell your parents about it, if they are loving parents (its sounds like they must be... you have had a very good example of how to be a loving person in a relationship) they will support you and care about you... ! whoever it is that you tell, tell them everything... tell them how you feel and why you feel that way and what you feel like doing about it and why you feel like doing those things. Be open and honest and don't keep anything inside. Keeping things inside will only lead you to have deep rooted emotional issues.
Learn from what has happened, don't turn it into something that will effect you for the rest of your life. Realize that this girl isn't a normal/good person, and not everyone is like that. People generally treat you the way they need to be treated... this may seem harsh, but that wench doesn't need someone who will treat her as nice as you treated her. She needs someone to treat her the way she treated you before she will ever realized what she did, but thats not your job.There are other people out there that will allow you to treat them the way you treated her and not take advantage of you for it.
yeha i guess i hear you when you tlak about not thinking anyone else will ever be as good as she was... i know that feeling real well, i loved my first girlfriend... but i love my current one even more... when i broke up with sierra i went through 2 other realtionships... and the entire time i compared them to my relationship with sierra... it was horrible... i finnaly decided to wait until someone just came along... finnally someone did, and im so fickin happy... there are other girls out there that will make you feel so much more loved than she ever did. i know you don't feel that way now (becuase you ahve been badly hurt), but their out there... you just have to be pacient :)

good luck man... i hope what i say helps :)
