It was rather nauseating. You know why? Because I am no longer interested in him. At all.
But at that time, all I knew was there stood a tiny doorway into a beautiful garden. All I knew was that I couldn't get in there.
"Alice opened the door and found that it led into a small passage, not much larger than a rat-hole: she knelt down and looked along the passage into the loveliest garden you ever saw. How she longed to get out of that dark hall, and wander about among those beds of bright flowers and those cool fountains, but she could not even get her head through the doorway" -Alice's Adventures in Wonderland by Lewis Carroll
I know that I don't see the whole picture, the future. But still, like Alice, I fixate on something (someone) I want and believe that it (a relationship with said someone) would be amazing. Part of that is hope. Part of that is complete nearsightedness.
Of course, despite my nearsightedness, I do know a few things about him and a potential "us", some gathered from direct observation, some from generalizations based on observation. Combine that knowledge with my flittering emotions (which are part chemistry, part natural-born desire for there to be something more), and BAM! *creeeeak* my scope swivels to the target and focuses in, because, as I said, I'm pretty sure this would be amazing if I could only have the chance to pass through the narrow passageway and through the door.
I actually think it's fine that our vision is based in hope and nearsightedness. If we waited to act until we had full knowledge and understanding, nothing would ever happen. Perhaps we often haven't acted enough even. Rebellions are built on hope, after all. Rogue One reference there.
But, facts being facts, we must concede that besides the few character traits we've observed, besides the flutter of emotions, we don't know much else. Faith is the substance of things hoped for, the evidence of things not seen--that has nothing to do with faith in a potential relationship. There is no virtue to holding on to an imagined amazing relationship by faith. We can pray and crack twigs and make ourselves available, but when it doesn't happen, we really had no idea if we were pursuing a lovely garden or, alternatively, a land filled with queens chopping off heads and slowly vanishing Cheshire cats (and I'm not saying the guy was a closet jerk--I'm saying we don't know what is best for him or for us). Our faith and hope and longing is not for the unseen future husband. It is for the only One who can see the end from the beginning (Is. 46:10), and who gives good gifts to His children (Mt. 7:11).
