He is so desperate for her to love him back. For her to even like him. For her to just not actively hate his guts!
That kiss - they've been married for over a year and I don't think he's even kissed her yet! And going off to battle, he had to take that chance, especially when she showed the teensy bit of care for his safety. And even then, it was a kiss on the cheek.
"I will never forget you saved my life." Not just his injuries!
