I can offer some possible explanations for the behavior you described, based on common human relationship dynamics:
Emotional Turmoil: After the fight, the person might have been overwhelmed by emotions and uncertainty, leading them to express a desire to ask you something but ultimately deciding against it due to fear, anxiety, or confusion.
Fear of Confrontation: They may have wanted to address the issue but found it difficult to have a face-to-face or direct conversation. Ghosting could be a way for them to avoid confrontation or difficult emotions.
Uncertainty about the Relationship: The fight could have triggered doubts about the compatibility of the relationship, causing them to withdraw to gain clarity on their feelings.
External Factors: Sometimes, personal issues or external circumstances can arise, diverting their focus and leading to unintentional ghosting.
Lack of Communication Skills: Some individuals struggle with expressing themselves effectively, leading to misunderstandings and ghosting as a way to avoid dealing with difficult conversations.
Testing Boundaries: It's possible that the person is testing how you react to their silence, possibly to gauge your level of interest or emotional investment in the relationship.
Regardless of the reason, ghosting can be hurtful and confusing. If you are comfortable, it's best to try and communicate with the person about how their behavior made you feel and seek clarification about the situation. Keep in mind that sometimes people may not have a good reason for their actions or may not be ready to communicate honestly. In such cases, it's essential to focus on your well-being and consider whether this person's behavior aligns with what you want and deserve in a relationship.
