I suppose it is stupid to think that some of the things that she does would make sense to a non such as myself.
I realized that she probably unblocked me out of surprise that I did not contact her on my birthday begging for her to return. I suppose it doesn't matter since I do not think of her anywhere as much as I used to. People are always curious to see what others are up to and that would explain the re-block. She got curious, saw that I am busy and quickly re-blocked me. Makes sense.
I am sure that I would think of her even less had I found someone I liked to date. I have plenty of people to speak to, not many dating prospects /yet/. I am on the verge of getting dates though.

It just boggles my mind that she had a great future with me and would blow it. Guess that's just her fuzzy thinking.
