Even though Renesmee didn't spend her birthday with her family or even her parents she was still happy with the fact that her mother was home for a while. Bella had to go back to California to advertise her new book that was coming out soon, so instead of taking off and coming back to Forks. Edward decided that they all go to California together support Bella and thankfully it was going to be during Christmas vacation.
Bella however still was having second thoughts of Edward, she still couldn't believe all the things he did to Renesmee so while she was alone in California for a while since she was picking up a few clothes and personal items to take with her back to Forks. She thought long and hard what she wanted to do and knew deep down that she still loved Edward because he was her first love and the first person to talk to her when she moved to Forks.
Edward felt guilty for the pain he caused Nessie and blamed himself for her actions. Because he knew the only reasons why she became rebellious through the years was because he never believed her when she told him what Tanya was doing to her. Plus, he blamed his family for not once telling him that they were still in contact with Bella because he would always tell them that he missed her and regretted doing what he did.
Renesmee was happy that everything was back to normal but still had some anger towards her father and decided to make it hard for him to gain her trust back and told him, it'll take a while to get it back. Using his words against him because he had once said that to her.
