Firstly you're not being fair to her by telling her you can stray but she can't. So start there: Level the playing field and tell her she's free to do as she pleases. Show a level of aloofness towards her. She is begging you to NOT chase her by her actions of being cold etc.

ON THE OTHER HAND: One of the reasons she may be going cold on you is because perhaps she wants exclusivity but you haven't been down with that. Not enough info was provided here to know whether this has been discussed between the two of you.

Yea, I guess she is. I'll try to tell her that:)
Just now she went back to her dance school, she won't be back uintill 2 months from now, even though she has the time. Now this is just, she plays the game right I guess, I play it wrong, Still it always seems like she is one stop ahead of me:( And whenever I get a solution, she is one step ahead of me agian.

Well, I doubt it, because then she would've visit or meet up more frequently? Now she has gone competely cold, and I've stopped seing the light at the end of the tunnel with her.

We have discussed some of this, like we agreed to start with friendship, and if it works, we build up to something more, but we are never going to friendzone eachother, if you catch my drift.

I can play the jalous hand though, only option I have left now, either that or play silent uintill she initiate contact and then try to play "I don't care" act. Or am I completely hallucinating?
Avoid replying to junk messages?
I know from my experience so far, that I should do almost the complete oposite of what I feel... Or so I think.

Much thanks for your help in this!

If I play the jalous card, I really fear that I will get the respons "You couldn't even wait 2 months to see me" /quit.

What if I have some awesome news to tell her? We share alot, from music to reminding eachother of upcomming birthdays, Should I just stop that? And let her feel how its like to really have me completely out of her life?
Im 100% sure now, that she get's a bad feeling when thinking of us now, and that is something I feel is important to change, If we quit now, won't that "bad feeling" only develope in a bad way? Im getting more cluesless the more I write and think about it hah

Sounds about right. You're learning. I've been there too.

Do Not play the "jealous card" if you want anything with her in the future.

In regard to the cause of her coldness, again, enough information has not been provided in the posts to know if it's because you were free to get with other people and she wasn't OR whether she felt bad that you weren't exclusive with her OR some other reason.

There just hasn't been enough information provided about the background of all this to give a solid suggestion for what to do moving forward.

Given the information I do have,..

If it's that she wanted exclusivity and is mad you didn't give it to her, give her exclusivity already. Although that ship may have already sailed given her cold demeanor.

In any other event, proceed with an aloof manner. Let her know implicitly all the fun you're having and the new women you are meeting and all that. The two of you are not seeing eachother = you get to do whatever the fuck you want and meet as many new cuties as you please. Don't text her back right away, don't be her buddy, be a man who she is missing out on because you might get hooked into something permanent by one of these new girls you're meeting. This MAY get her to chase you and try to see you as opposed to leaving town for 2 months and not giving much thought to it.

After so much failing I must be doing something right soon
How can I show her I’m having great time and can do whatever I want without playing the jalous card?:(
Ok, I will try to explain the entire thing in short sentences

I. Got together 2 days after we’ve first met (Facebook texting success)
II. Things were great, no issues, no problems or fights for 2 years.
III. Joined the navy, while I was having familiy troubles, reducing my energy and attention to her a lot. Uintill It drove her away
IV. She broke up, Because I prioritized computer,, not wanting to get to know her family or paying enough attention to her. Well she did not say that directly, but I know that was the reason
V. Started working out for full, quitted computer, TV etc., to make a change, to prove myself and her a point.
VI. Got obsessed with her, lost my game, begging, trying to fix it all, yea, a total mess.
VII. Followed the Micheal fiorë program (Txt your ex back) consisted of 2 months of practicing, digging up old stuff, tons of things actually, I managed to stay out of touch with here having various girls in the army
VIII. Finished my time in the navy, found a new girl (hiding away all my feelings towards my ex for a year)
IX. Started going public with this new girl, showed this girl the time of her life and made her completely obsessed with me, even though all I wanted was someone there for
X. My ex made a move, resulting in me ditching the new girl and getting intimate with my ex again
XI. I wanted more, she wanted us to stay like this(Special FRIENDS, since she was had this big guilt for suddenly rushing in to my life, make me abandon this new girl, and she felt like she was ruining it all, she tried to back off again, but weeks of work on my side made us stay as special friends)
XII. Feelings rushed back, I didn’t accept only “special” friends and pushed her way too far, realizing that I was loosing her, but I have a cloudy mindset when it comes to her and I couldn’t stop it
XIII. It got too much of her, making her act cold to me for months, resulting for me to get intimate with other girls again. Also made me build up a lot of frustration towards her
XIV. I called her, telling her “I can’t stick around and wait for you, I can’t even recognize you anymore, you are way too cold, and I’m not staying put anymore” (Obviously more was said, but that was my message to her,) Resulting in that she didn’t want to lose me, and coming up with this “friend” idea. Moreover, our agreement starting as “friends”, building our way up with the time, if we both see the light in the end of the tunnel. I only said 1 thing to that friends agreement “If you ever friendzone me, I will never forgive you” This call thingy happened 2 days ago.
Yea, that as pretty much it in short sentences 
I totally agree with you! Proceed with an aloof manner, but when do I start?
Weeks? Days? This weekend?
Show her my life rocks even without you through facebook or snapchat?
You still mean this the correct way, even after this new information I provided?

Excluvity has sailed I know, she has way too bad impression of me now, I can't be at all attractive to her, maby only because she knows I truly care about her, but that is all the leverage I have. The negative impression she has on me is way bigger

Thank you so much for great replies!

Ok that clarifies the whole situation.

By "jealous card" I thought you meant you were going to show her that YOU were jealous of her. Yes by all means play the jealousy card such that she becomes jealous of the fun you are having, and do it asap. Move on with your life.

If she contacts you just play it totally cool like you are unaffected by her, like she is a good special friend as you call it.

There is nothing in your agreement that states you can't go out and meet more women, so do that.

FB, snapchat, fine, just don't rub it in her face. Have it be subtle. Be unavailable. DON'T TEXT HER BACK EVERY TIME SHE TEXTS YOU. Let her wonder what you're up to. If she says "why haven't you been texting me back all the time" just say "hey : D been super busy lately".

See if she chases you and offers to come and see you as opposed to her being away for 2 months and not caring one way or another.

Thank you for great reply!

I will play the jaelousy card, but not too far, last time i did that she told me "You did all the things I wished you would do with me to other women"

I'll set my plan in motion asap, got a date for friday, I will start my move now! thank you for help, and I will keep u uppdated on this thread
