I'm glad this struck others off beat as well. Kaladin and Shallan don't have live the happily ever after for me to be satisfied but I really dislike the Shallan/Adolin relationship as presented, and maybe thats intentional by BS. Kaladin is the only person around that least recgonizes that the "Shallan" we have seen is just another mask. Adolin doesn't recognize her, he just recgonizes the Shallan mask, and worse, validates the personality split by treating veil differently. This is just wrong on so many levels, he doesn't love her, faults and all, he loves the Shallan mask.
I do think Kaladin was drawn to her because of his brother. There was a mention somewhere in the book about another proto-radiant being among Amarams army, but that they had perished before they needed to be dealt with. I think Tien was a proto-lightweaver, remember his beautiful horse carving (when he should have been making a chair) and it's implied that Kaladin thinks that similarity is what he felt in his connection with Shallan, so maybe a strong friendship is all there is there, and that is ok. But the Adolin/Shallan thing... Ick.
