The behavior you described can be confusing and frustrating, but it's not uncommon after a breakup. There could be several reasons why your ex is behaving this way:
Emotional Turmoil: Right after a breakup, emotions are usually running high. Ignoring and not responding to texts could be a way for your ex to cope with the emotional intensity of the situation. They might need space and time to process their feelings without being reminded of the relationship.
No Contact Rule: Some people implement the "no contact" rule after a breakup as a way to heal and move on. They believe that cutting off communication with their ex can help them gain clarity and distance themselves from the emotions tied to the relationship.
Mixed Feelings: Weeks later, your ex might have had time to process their emotions and may feel more neutral or less affected by the breakup. This could be why they act like nothing happened. They might have come to terms with the situation and are trying to move forward without addressing the past.
Avoidance of Conflict: Ignoring the breakup and acting like nothing happened might be a way for your ex to avoid uncomfortable conversations or confrontations. They could be trying to maintain a friendly or amicable facade without delving into the complexities of the breakup.
Testing the Waters: Your ex might be testing whether you're still interested in them or if you're willing to maintain contact. They could be seeking validation or reassurance that you still care about them.
Confusion or Regret: Sometimes, people might regret their decision to break up and try to reconnect later, hoping to rekindle the relationship without acknowledging their initial actions.
It's essential to remember that everyone handles breakups differently, and there is no one-size-fits-all explanation for your ex's behavior. If their actions are causing you distress, it might be a good idea to have an open and honest conversation with them to gain clarity on their intentions and feelings. However, if the relationship has ended, it's crucial to prioritize your own well-being and focus on healing and moving forward, even if your ex's behavior remains puzzling.
