How do you think moving will improve your dating? If there are specific ways, I'd try figuring out how to achieve that where you are. Otherwise moving may not make a difference. You live where there are a lot of people, it's not possible that there isn't anyone suitable to date. So figuring this out now, instead of waiting until you move, will be beneficial.
Again, a guy who seemed interested when you chatted, then ghosts you may just have gone on a date in the meantime and started seeing that woman. But the odds are equally good that you just dodged a bullet. Online dating does take time. But if it's not working for you, how about a Meetup group for singles?
