This one was okay. I agree what the woman did was pretty selfish, but on the flip side, I think he was blind to what she wanted as well. Or maybe I'm reading too much into the line "You were right...it's probably better not to have kids." Sounds to me like she wanted kids at one point, but he talked her out of it, and that was the point where she started craving more to life than he was capable of giving. But that's just my opinion.
The sad thing though was that instead of moving on, he was so fixated on her that he forced himself to change into something else, not for his peace of mind, but to try to understand her. By the time he found her, he had completely lost himself. Very sad.
I loved the bit with the fey actress. Any actress that sleeps with a knife sounds cool. Would love to see more of her.
