Benjamin bailed- It's OK to be different

I just saw the Benjamin Button flick. Great film, awesome acting. So... what do people think about Benjamin's choice to leave when his daughter is one? I think he should have stayed and trusted it would work out. I am sick of people, characters, movies playing it safe, doing the martyr thing and then saying they did it for the kid's best interest. Gimme a break. Why are people so afraid of stepping out of the box? He would have been a great dad. What about the effect of Cate Blanchett's character still being in love with Benjamin and not her husband. Do we honestly think that that does not effect the child- that the kid would not pick up on that. What are they modeling for their child- selflessness or self-denial? I think he just could not stand being happy and this gave him a way out. It's OK to be different Benjamin!
