Need to get back with the ex!!!!

I was in a relationship for 2 months with an awesome girl with whom i fell in love with. In the first 6 weeks she was crushing me with attention, we were spending almost all the time together, sleeping at her place or mine. Then she went home for one weekend and when she came back she felt kinda cold...30 mins/day together tops, never sleeping together. This behavior seemed rly strange and i told her that and she replayed that its not bad either to miss each other...i agreed.Waited for a week then she went out with a friend shopping, came back and left me a message that she was going to go out again, clubbing .I got mad and said i waned to talk...went to her place(she and her friend were getting ready to go out) i waited a bit but she didnt pay too much attention to me so i got mad and left.Then she called me and asked why did i leave so upset and if it was caused by her going clubbing w/o me(ofc i wasnt, i mean i was gna go out with just my male friends at a point as well).And i told her that its not normal to spend this little time together and it feels like it started after i said that i fell in love with her.She said that we should talk tomorrow.She went out, came back and didnt even came by to say so and went from idle to invisible on ymsn.(She lives 1 floor above) I went for a smoke with a friend and heard 3 guys going down and her saying goodbye to em.At that point the jealousy hit me...went up and knocked at her door but no one answered. Sent her a text that i heard her 10 mins earlier and i dont understand why she didnt answer and i deserve some explanations.Nothing
Next day after i sent her another message where i said that i waned to get my things she called me...we talked and she explained her behavior as her being a selfish and difficult person which, now, feels like being 24/7 on same place with me and then she may feel like never seeing me for 1-2 days.That she'd never mess with me or cheat on me. All was fine till 5 hours later when i needed some pills...knocked at her door no answer, on ymsn she appeared offline where i left her a message that i went to her door but no one answered and to get me the pills when she sees it. She was on invisible again and took the message as a check if she was online or not.So its better to break up and stay friends cuz if we continue she'll blame me sooner or later for what i've done and she doesnt want that.I told her that im ready to take that risk still no good . Made several mistakes where i texted her and said that i still waned to be with her, how much she meant for me and stuff like that...ofc no good came out of it.After 4-5 days we had a calm discussion where we kinda agreed to be friends she also told me that i look good. I told her that my only regret was that the relationship ended so soon...she said she felt the same.She told me that she still had feelings for me as do i but its still for the best to breakup.Kissed eachother on the cheeks and she gave me a big hug.She also was very affected by the fact that i removed her from friends on facebook...We haven't talked since...should i re-add her on facebook now or wait more? I started working on my jealousy problems as well.
How can i Get Her Back? I feel so bad cuz i rly miss her.
Any advice is much appreciated and thanks for reading

Do not talk to her anymore, I it will be hard to do and you will have à hard time doing but you have to. She'll come back to you when she realize that can live without her, be happy with it, or even better if she sees that you can replace her. I know it sounds counter productive but that's the way women work

Yes, i was doing this...just hope it works and her pride won't get in the way.She left me the impression that she's the kind of person that makes impulsive decisions and sticks with them.Which leads me to believe that its still me who should initiate at a point.

Drh but this scenario is pretty common a lot of guys went through this and trust me be that man who is strong rough to move on and not to talk to her anymore she'll chase you back. If she doesn't for any reason then fark it you deserve better than that and you have thé tools to get plenty of girls anyway. She has been disrespectful and bitchy so she has to come to you and apologize, if she doesn't then she's not worth it forget her and replace her (then she will chase you back)

Thanks a lot, what u've said sounds good but i'd like to hear some more opinions first.
Anyone else? any advice is most welcome

After listening to "lock-her-in-and-keep-her-attracted-to-you" I realized that I was kinda an AFC,gave her most, if not, all the power and she most likely lost interest and found me boring. Now i want her even more out of ego, probably, to prove to myself and to her that I'm better than that + feelings i still have for her. I know it takes a lot more energy to convince her to get back than to pick up a new girl but at this moment i see this as a useful experience and on the other hand i'm glad she dumped me cuz it opened my eyes soooo hit me!

Yeah and trying to come back to her will make it worse. Non neediness is the key.

Well i didn't say that i was going to go crawling back and beg for a 2nd chance saying i changed and crappy stuff like that to show weakness.Just that i'm more eager to Get Her Back now no matter how i do it. :P

Yeah and you can totally Get Her Back but its not gonna be easy because you'll have to do stuff like ignoring her, not caring about what she does and where she is going .. while raising your own value by going out, having fun ... That can do it IMO
