I think I understand what FS is looking for, but I would strongly caution that unless you are able to perform a Vulcan mind-meld, "unspoken" assurances and assumptions can lead a relationship into trouble. At some point you have to check in with each other, or it's a sort of emotional parallel play. You don't really know what's going on in there, and neither does she.

Also, at some point people can actually become what they start out only pretending to be.
