I can offer some possible explanations for your ex-boyfriend's behavior based on common scenarios:
Accidental text: It's possible that your ex-boyfriend sent the text accidentally, and upon realizing it, he deleted it before you could read it. This could be a simple mistake, and he may have ignored your reply because he didn't see the need to explain the situation further.
Emotional hesitation: Your ex-boyfriend might have intended to reach out to you but had second thoughts about it or felt unsure about how to proceed. Deleting the text and ignoring your reply could be a sign of emotional hesitation.
Testing the waters: Some people might send a text to their ex to gauge their reaction or see if they are still interested in maintaining contact. If they don't receive a strong response, they might choose to ignore further communication.
Mixed emotions: Breakups can be emotionally complicated, and it's possible that your ex-boyfriend is experiencing mixed feelings. He might have reached out impulsively but then decided against pursuing the conversation.
Wanting attention: In some cases, an ex-partner might send a message just to get attention or a reaction from you. Deleting the text and ignoring your reply could be a way to keep you guessing or to assert some control over the situation.
It's essential to remember that speculation can only go so far, and the only way to truly understand your ex-boyfriend's intentions is through open and honest communication. If you feel comfortable doing so, you could reach out to him directly and ask about the deleted text. However, if you're not ready to engage in further communication or if the situation doesn't feel right to you, it's okay to take some time for yourself and focus on your own well-being.
