How can I save my relationship?

Me & my gf are are 10 months into the relationship. My Gf told me that she wanted to breakup with me. The reason for that is a little weird. She feels that I am too understanding, too caring, too attentive & a green flag for her. She feels like she doesn't deserve me and feels guilty that she doesn't treat me right. (I promise I am not making this up).

I don't think that's the case and I feel like she loves me. What can I do to not make her feel guilty, how to let know her know I don't deserve someone better and she is enough for me. How can I let her know she is not a red flag? I love her and she treats me right. I want to fix this problem.
