I'm sorry to hear that your ex-boyfriend didn't reply to your text. While I can't know his specific reasons for not responding, there could be several possibilities:
Emotional Healing: After a breakup, people need time and space to heal emotionally. Even after the 14 days of no contact rule, he may still need more time to process his feelings and emotions before engaging in any conversation.
Moving On: He might be trying to move on from the relationship and doesn't want to rekindle any feelings or memories by responding.
Avoiding Conflict: He could be avoiding a potentially difficult or awkward conversation with you, especially if he was the one who initiated the breakup.
Mixed Feelings: He may have mixed feelings about reaching out to you, unsure of what he wants or how to respond.
Busy or Preoccupied: He could be occupied with other things in his life, such as work, personal matters, or other relationships, and hasn't found the time to reply yet.
Not Ready for Communication: It's possible that he's not ready to communicate with you again, either because he's still upset about the breakup or because he wants to maintain distance for personal reasons.
Remember, everyone processes breakups differently, and there's no one-size-fits-all answer to why he hasn't replied. The best course of action right now is to respect his decision and give him the space he seems to need. If he wants to talk, he'll reach out when he's ready. In the meantime, focus on your own well-being and healing process.
