It's challenging to determine the exact reasons for your friend's behavior without more context, but I can offer some potential explanations for her actions:
Misinterpretation of Emotions: It's possible that your friend might have difficulty reading social cues and misinterprets your expressions or body language as anger, even when you are laughing or being normal. This could be due to her own experiences or insecurities, leading her to project her feelings onto others.
Insecurity or Need for Validation: Some people constantly seek validation from others and may ask for reassurance about their relationships. Your friend might be seeking reassurance that you're not angry with her to ease her own insecurities.
Changes in Friendship Dynamics: If your friend recently made new friends, she might be feeling a shift in the group dynamics. This change could be making her more sensitive or anxious about her relationships with her existing friends, leading her to seek reassurance about potential conflicts.
Feeling Left Out or Neglected: When you mention that she was nice when nobody talked to her, it's possible that she felt left out or neglected during that time. As a result, she might have become resentful or defensive, leading to changes in her behavior.
Peer Pressure: Sometimes, when people make new friends, they might adopt certain behaviors or attitudes to fit in with the new group. This could result in changes in personality or demeanor.
Personal Issues or Stress: Personal issues or stress in her life could be affecting her mood and behavior, leading to increased sensitivity or a change in personality.
Whatever the reasons may be, it's essential to approach the situation with empathy and understanding. If you value your friendship with her, consider having an open and honest conversation. Ask her if anything is bothering her and if there's a reason she frequently asks if you're angry. Communication can help clarify any misunderstandings and provide an opportunity to support each other better.
If her behavior continues to be hurtful or disruptive to your friendship, it might be necessary to set boundaries and evaluate whether the friendship is healthy for both of you. Healthy friendships are built on mutual respect, trust, and support. If your friend's behavior becomes consistently mean or toxic, it's essential to prioritize your well-being and surround yourself with positive influences.
