Why my girlfriend answer anytime I call her baby but doesn't want to tell me she loves me? ?

It is possible that your girlfriend may have difficulty expressing her feelings or may not be ready to say "I love you" yet. It is important to communicate openly and honestly with your partner about your feelings and concerns. It may be helpful to have a conversation with her about your relationship and how you both feel about each other. Remember that everyone expresses love and affection in different ways, and it is important to respect your partner's boundaries and feelings.
