What is why does she get jealous if we are just friends?

Jealousy in friendships can occur for a variety of reasons, and understanding these can help address the situation positively. Here are some possible reasons why a friend might feel jealous:

1. Insecurity: She might feel insecure about her own value in the friendship or worry that she might be replaced by someone else. This is often based on a fear of losing the connection you share.

2. Attachment: If she values the friendship highly, she might be protective of it. This can sometimes manifest as jealousy if she perceives a threat to the bond.

3. Perceived Imbalance: If she perceives that you are investing more time and attention into other relationships, she might feel that the friendship is imbalanced, leading to feelings of jealousy.

4. Past Experiences: Previous experiences with friends or relationships may influence her current behavior. If she has been betrayed or sidelined before, she may be more sensitive to situations that seem similar.

5. Unspoken Feelings: There might be deeper feelings that she hasn't expressed, such as romantic interest, which can make her more sensitive to your interactions with others.

6. Comparison: If she compares herself to your other friends or even feels competitive, it might trigger jealousy. Social comparisons can sometimes lead to dissatisfaction and envy.

Addressing jealousy involves open communication. Encouraging an honest conversation can help clarify feelings and reassure her of the importance of your friendship. Being empathetic and understanding can go a long way in strengthening your relationship.
