I can offer some general insights that might help you understand why your ex might be feeling angry or upset even if you believe you're not doing anything wrong.
Emotional processing: Breakups can be emotionally challenging for both parties involved. It's possible that your ex is going through a range of emotions, including sadness, resentment, and anger. These feelings might not necessarily be directed solely at you but rather at the situation as a whole.
Unresolved issues: Sometimes, there might be unresolved issues or lingering feelings after a breakup that contribute to the anger. It could be that your ex is having difficulty moving on, and seeing you or interacting with you may trigger those emotions.
Different coping mechanisms: People cope with breakups differently. While you may be trying to give her space and avoid confrontation, she might process her emotions in a different way. Some individuals might express their pain through anger or frustration.
Perception of the breakup: Even if you believe you're not doing anything wrong, your ex might have a different perspective on the events leading to the breakup or the way it occurred. She may have different expectations or feel hurt by certain aspects of the relationship's end.
External factors: Sometimes, external factors in her life might be contributing to her anger, and it may not be entirely related to you. Personal issues, stress, or other challenges could be influencing her emotional state.
Loss and change: Breakups signify a significant loss, and some people react with anger as a way to protect themselves from further emotional pain or vulnerability.
It's essential to approach this situation with empathy and understanding. While you may not be the cause of her anger, it's essential to give her the space she needs to process her emotions. If you want to have a conversation about it, try doing so in a calm and non-confrontational manner, focusing on understanding her feelings rather than justifying your actions.
If her anger seems excessive or unhealthy, it might be beneficial for both of you to seek support from friends, family, or even professional counseling to help process the emotions and move forward in a healthier way.
