Summarize the following:
They may be physical, intellectual, emotional or spiritual. Discussing the positive feelings she had towards you in the first place will encourage her to embrace those feelings again. Try saying, “I'm just curious…what was it about me that you were interested in when we first met?” Tell her that you're there to listen any time she wants to talk. If she is willing to talk, give her your full interest and attention. Don't rush her or try to offer easy solutions; she'll feel more heard if you just listen and reinforce that you support her choices. Try saying, “I understand your feelings,” or “I support you.” Without bragging, subtly work into your conversation ways that you're working on yourself. Tell her something new you've learned, and how it's expanded the way you look at things. People tend to be attracted to others who are intellectually engaging and interesting.  For example, if you've done well at work or in school, casually mention it. Try saying, “That reminds me of something I read about the other day…”

Summary:
Ask her what qualities she initially found attractive in you. Pay attention to her. Convey that you're improving yourself.
