i think he really does know. firstly, because in italy, he held on to her, and he really tried to not kiss her or anything huge. then he stayed the night after too. then, after she woke up, when he took her to his house, and she told him he was the first worry, i think it finally occurred to him "oh crap, it really hurt her more then it hurt me." and also, i think he understands because he was pretty much going through the same pain, and he also thought that bella had gotten over him.
oh, and freekin team jane! hope she finds a nice vampire boy thats not quite as hot as edward, but pretty freekin close!
