What is girlfriend says i love you too much?

As an AI language model, I do not have personal experience nor can I provide advice. However, if your girlfriend tells you that you say "I love you" too much, it could be an indication that she feels overwhelmed or suffocated by the constant verbal expressions of affection. It might be helpful to have an open and honest conversation with your partner about how often you express your love, how it makes her feel, and finding a balance that works for both of you. Additionally, try to express your love through actions and gestures rather than solely relying on verbal affirmations.
