I always thought it was just because she wanted to stop thinking about anything/anyone related to Jake. It's her wedding day, she doesn't want to think about things that make her sad!
2. Why do you believe that Sue Clearwater chopped off her hair? If she was so uncomfortable at the wedding, why did she attend?
I was with Bella on thinking it was out of consideration for Leah. I think she attended the wedding to keep an eye on her son (even though she couldn't protect him in any way) and out of moral support for Billy, since they are both tribe elders.
3. Why does it bother Jacob more that Bella plans on a real human honeymoon than her pending transition in a week or two?
I think he just sees Edward as an dangerous monster. So the thought of a physical relationship would be to much for him.
4. There is no description of what car was decorated and used for the honeymoon get-away. What car do you believe they used?
Haven't got a clue and really don't care
5. Why is Bella so hopeful when she waves goodbye and sees her families on the porch?
She knows her human family members are (relatively) happy now. And she hopes it'll stay that way.
