From a psychological point of view, the phrase "girlfriend" may reflect an emotional state called "loyalty test" or "loyalty test." Loyalty testing is a psychological concept that refers to a person's expectation of their partner. They want their partner to be loyal to them, regardless of whether they really like this person or not. In this case, the girlfriend shows that she has accepted her attitude towards true love and fake love, that is, she hopes that her partner can treat her in a loyal way, regardless of whether her feelings are true or not. There might be an emotional need behind the phrase girlfriend. She wants her feelings to be recognized and she believes that her partner truly loves her. This need may be due to her uncertainty about her feelings or she may be experiencing a period of emotional fatigue and need a way to prove her partner's loyalty. It should be noted that this sentence does not necessarily mean that the girlfriend is not sad, but she uses this sentence to express her emotional needs and also to show that she wants her feelings to be recognized. If her partner doesn't really love her, she might feel disappointed and sad. But she chose to express her feelings in this sentence instead of telling you directly how she feels, which means that she still trusts her partner and wants to continue the relationship.
