I also want to add one thing ...
he is NOT perfect as everyone claims him to be .. ofcourse he is not .. he has made soo many mistakes in his life ... ooops, his existence I mean!! lol..
he ALWAYS gives in to bella's demands no matter how stupid they are .. and he has to face the consequences later .. like letting her give birth to their half human half vampire daughter .. and almost letting her get herself killed in the process...
he left her alone in the dark woods .. for her own good .. without thinking abt the fact abt what she wud be like after he is gone .. even if it was for her own good...
and ofcourse ... the way he was initially possesive of bella when she wanted to be wit jake ...
but somehow..he has always managed to make up for his mistakes .. n if not, atleast accept them and be ready to face watever punishment he deserves for commiting them ...
one line which sooo DEFINES him for me is --
"when I left u Bella, I left u bleeding. Jacob was the one to stitch you back up again. That was bound to leave its mark-on both of you. I;m not sure those kinds of stitches dissolve on their own. I can't blame either of yyou for something I made necessary. I may gain forgiveness, but that doesn't let me escape the consequences."
