It's a way to help her rationalize everything. She dumped you, she didn't want to be in this but she is trying to play the victim and post all these sad posts to get attention and comfort. From you, from anyone. If that's what she wants to do, let her. It's counterproductive for her own growth and being if she is convincing herself she had no responsibility in this. Haunting her facebook statuses isn't helping you, it's causing you to read into her and keep you thinking about her. Remember, this is what she wanted. She is not facing the consequences if you are still chasing after her and giving her comfort. AS IF YOU OWE THIS TO HER? Doesn't that piss you off a bit?
It seems you read the books and you know NC is good but you don't seem to understand WHY it's good. I know you are dumped, it hurts, it makes you feel like a failure and now is the time to fight and fix and make everything right. So you are looking for any tactic to work in your favor. NC is not a tactic to get her back. It can have that effect to get her to reach back out to you in loneliness, but that is not the point. The point is to ween yourself off the dependency you have to her. To rediscover who you are, what makes you happy, and to become that happy person that you were before when you guys first got to know each other and fell into love. Even if things seemed okay at that lunch you took her to, it wasn't 100 percent. It wasn't completely normal: it was awkward because you guys aren't together but you are acting like you are. It's not the same falling back in love feeling. The relationship is broken, she wanted to leave and you are trying to lure her into a broken relationship again. A couple weeks is not a long time in the big picture, and it's hard for her to miss you if you are always checking in and are always there for her.
Waking up next to a beautiful girl,
Step outside and say hello to my beautiful world.
