I completely agree. I also don't think it would be healthy. Kaladin needs someone to balance him, not to set him off.
If Jasnah has any relationship I would probably assume it to be platonic as she is a mainly cerebral person to whom bodily needs are (excuse the pun) somewhat immaterial. We can also see this in her powers: she can travel to the cognitive realm and she can transform matter (thus becoming aware how mutable and impermanent the material world is). On a purely practical level she is now acting queen of Alethkar which if we know Jasnah at all she will take supremely seriously. I doubt that (even if she were so inclined) she would let a mere romance distract from her new duties and studies. All that aside I also don't see it happening with Kaladin at the moment as I think Jasnah views him as quite immature on some points of reason and the two of them disagree on a few very fundamental concepts. I see Kaladin moving more towards a potentially widowed Laral, a Windrunner page, or a character that has barely/not jet been introduced. In general, both Jasnah and Kaladin currently have way more urgent stuff on their plates than romance...
