Dont try to make sense of the crazy, it's only going to drive you crazy. All those questions you have asked, has been asked on here hundreds if not thousands of times. Most people when they first come to this forum is trying to find the "why", they try to figure if this or that happened or didn't happen, things would be a whole lot better. After a while though, most people realize the why doesn't matter, and if you DB right and save yourself, one-day you might get your why from your S or you might not. But in the end you are a whole lot better.
The comment about you could take your W back. Every person that comes here says that statement as well. The longer the DBing goes on and the longer limbo goes on, people feelings tend to change. I will tell you take each moment for what it is, because your feelings will start to change multiple times in a day. "I want to be with her, I don't want to be with her. I'm going to move on. I'm going to stay. I truly love her. I hate this person she is now." You will go back and forth. I'm telling you this so you can be better prepared to react and handle those feelings and emotions.
Keep posting.
