Think being outta of sight , outta of mind, is okay. Because a hyperfocus is not good. I am sure that NT's don't think about the one in their love life constanly.
Perhaps being on the spectrum, it's rather hard for others to grab our interest, because we need to be engaged on many different levels. Our senses, our imagination, our logic, because some of us are very sensitive. It's rare that l find that person that really grabs me and l chose not to settle for a blah relationship. And l chose not to be in a relationship purely for just that reason. Is this love? It's a journey to discover myself and that person and enjoy our interaction.
