I love Rose to death, but she was selfish and short-sighted. After Dimitri's journey to hell and back, she expected an overnight recovery. After all that time taking care of Lissa and worrying about her mental health, Rose should have been more understanding of the psychological damage he'd suffered from being turned Strigoi and then restored. It must have been terrible feeling so alienated from him, but he needed time to heal, and she didn't respect that. She kept following and harassing him, trying to make him declare his love for her.
