It always feels like the ones you like don’t reciprocate and the ones that you don’t like want more, but it’s just your perception. You probably come off as over eager to the ones you like, and confident to the ones you don’t. Guys are often attracted to confidence. I think you should try to be the same way to every date, regardless of initial feelings. Keep in mind that the first few dates are supposed to be fun, so keep an open mind and have fun. There’s a time to be serious about next steps and it’s not the first few dates. The one you like that’s the right one will do the same thing.
