If you are in the talking/ getting to know each other phrase of a relationship, and the only downfall is a lack of communication from the other party

Communication is everything in a relationship. Without that, there is nothing to pursue.

Best to move on. It’s too awkward and uncomfortable when it’s one sided.

It has to be two way to be COmunnication. "Danger Will Robinson!"

Idk..maybe!

If it’s one-sided, you’re already seeing what it is. People tend to give most of their attention in the beginning, so if they’re short on communication now that’s unlikely to improve.
