If your ex cheated on you and then expressed that they don't want to talk about it, it could mean a few different things:
Guilt and Avoidance: Your ex might feel guilty about their actions and may not want to face the consequences or have a difficult conversation about the betrayal. Avoiding the topic could be a way for them to avoid feeling remorseful or dealing with the pain they caused.
Lack of Remorse: Another possibility is that your ex may not truly regret their actions and, therefore, don't want to discuss it. They might be indifferent to your feelings and not care about the impact of their behavior on you.
Protecting Themselves: They could be trying to protect themselves emotionally by avoiding a confrontation or discussion that could lead to more negative feelings and potential repercussions.
Fear of Losing You: Sometimes, people who cheat and are caught may fear that talking about it will lead to a complete breakup or loss of the relationship. So, they might avoid the topic to hold onto the relationship, even if they are not willing to address their actions properly.
Regardless of their reasons, it's essential to prioritize your well-being and emotional health. If you feel the need to discuss what happened, closure, or resolution, consider talking to someone you trust or seeking support from a therapist or counselor. It can be beneficial to process your emotions and gain clarity about your feelings and the situation.
