if she wants a break its more than you don't show your feelings to her. if it was that reason, im sure she would have told you several times to show her more attention and you seem like you are now so that would have fixed the situation. if she told you already several times and you haven't changed and it took her threatening to make you turn around, she may be contemplating breaking up. a girl wants someone who when she has been with them for 2 years and expresses something of concern to him, she wants to be taken seriously. if it is her saying this for the first time, there has to be something more to it and you need to find that out. and if there is no more to it and she wants a break over this and she is didn't not sit down and talk to you about it before it came to this, that's not fair and you deserve better. you don't need someone who threatens to get results. you need someone who after two years can come to you and tell you whats bothering her and be willing to work through it with you before just giving up with out talking to you. so i would give her her space, don't tell her your giving her space, and when she calls tell her how you feel, tell her you want to talk and see if things can be worked out and take it one step at a time. good luck.
