How could a guy like me a lot, but not be interested just because I message him too much and like him too much?

I was never that way, if I liked and was interested in someone and they showed little or no interest I'd move on. The worst thing a woman could do was play hard to get, because if she was interested then she would miss out. Now there is such a thing as being too eager or aggressive, but if a girl/woman was interested I would have loved for her to let me know it (maybe even approach me for a change...nothing wrong with the female making the first move). It never happened, but that's how I always knew I'd know when I met the right one...and that's exactly how I got with my wife.
