my iitial reaction is you probably are too good for her and if she that fickle with your feelings you are best off out of it forget her and move on

Just reading the initial post, it sounds as though she got the impression that you were not going to, and didn't want to fight for the relationship. Maybe if you'd had a real argument with her...I don't know. Sometimes women are just batshit insane.

Women. You can't live with them, go to jail if you shoot them.

It seems to me that she used a different version of a well known line "It isn't you, it's me". We all use this line when we don't want to hurt the other person and want them to think that we are the one at fault.

She needs her space. There just might be another guy on the scene but it's just as likely that there isn't. Don't push things. Don't contact her. I known it's difficult just to switch off and I'm not saying you should or suggesting you can. What I'm saying is that you must take a step back.

Good luck!!!

its best to do nothing. either she'll come back regretting her actions or she won't. my ex kind of did the same to me. although at least she phoned but it was 24 hours b4 she was supposed to coming to see me. suddenly over and she couldnt say why. people would say she did know why but didnt want to hurt me but she is the sort of person that wont think about stuff. I mean being too scared to look inside. So like if she's unhappy about something, which in retrospect she clearly was, she wont deal with it until it builds up and she can't take it anymore.
The irony of the situation is she didnt seem relieved at all, infact the complete opposite. Anyone would think I'd broken up with her. She was in a "ive broken it and dont know how to fix it" state. I did try to get her to talk about it but she wouldnt but at the same time wanted to be friends and still communicate. In the end I had to leave her to her own devices and not speak very often.

Putting myself in a position of strength seems to have done the trick as she wants to see me again and that gives me leverage to try and sort out why this happened and how to fix it as she freely admits that she hasnt stopped loving me. She is an honest and open person so I know when she tells me she hasnt been with anyone else its true and the the conversation that went she's been telling her friends how much she misses me, and they're asking why she doing this and she's telling them she doesnt know, is also true.
Well anyways im being careful about letting my emotions run off and get too hopeful as its all very tricky when dealing with someone who doesnt know their own mind properly. And no matter how much I really want to be back with her got to maintain the position of strength.

the moral of this story is put yourself in the position of strength. its good for you mentally and tell yourself and everyone else that you may still love her but if she wont be reasonable its her loss. The only hope you have is for this to get back to her and the perception is you're the strong one.

A note on being nice.
Being nice tends to mean laid back and laid back tends to mean going along with stuff which sometimes means compromising your independence for someone else. This creates an incorrect perception that we're weak. Which is often wrong as when we're bothered about stuff we wont stand for it but its nails in coffins if this perception gets too pervasive.

it occurs to me just now that the reason why good looking women want "bad boys" is their natural ability to maintain independence and at times indifference. This makes the woman who know's she's good looking and can have a strong personality have to work for it. There can be only one strong person in a relationship at any one time. I imagine lasting relationships are where there's a status quo either one is naturally dominant and the other naturally submissive (my parents seem like this) or there's a balance.

it further occurs to me my relationship partially went pear shapped because I stopped being independent enough and kept defering to her whims, at a time when situations changed. There's a reasonable chance If I can get her to come and see me and be the strong one and stay independent it'll work out for the best.
