Congratulations for the new job. I didn't read you "book" because it was long, and I lose track with long readings. I don't think you are undateable. I think you haven't met the right person yet, especially you think you are doing well. I think it is natural to face some declines and rejections. Not all people are compatible. Can you give me a glimpse to the story to get a better idea: why he didn't want to date? did you find him compatible to your level of intelligence and education, has similar interests, ... etc?
