I want to believe this relationship is right, but I can't tell if I actually see it clearly or if I just want it badly. What should I be looking at?

“The simple believeth every word: but the prudent man looketh well to his going.”

Proverbs gathers the training an Israelite father gave a son heading into adult decisions, in a world where a bad match shaped a whole life and could not easily be undone. This saying sets the credulous person beside the prudent one, who slows down and studies where his own feet are going. It does not shame longing. It asks whether you have looked at this person's actual pattern, or only at how they make you feel.

“Prove all things; hold fast that which is good.”

Paul wrote to a young church in Thessalonica that was buzzing with prophecies and competing spiritual claims. His counsel was neither to swallow everything nor to reject everything, but to test it and hold on to what proved good. That instruction was about spiritual claims, and it transfers to the claims a relationship quietly makes about itself. Testing something you love is not disloyalty, it is how you find out whether it will hold.
