I cannot know the exact emotions or intentions of your ex-boyfriend, but I can offer some possibilities for his lack of response:
Anger or Hurt: It's possible that he felt hurt or angry when you unfriended and unfollowed him after the breakup. He might interpret these actions as a sign of rejection or that you wanted to cut him out of your life completely.
Moving On: During the seven months of no contact, he might have moved on with his life and may not feel the need or desire to re-engage with you.
Resentment or Indifference: He could be harboring negative feelings towards you, which could be leading to his lack of response.
Avoiding Conflict: He might be avoiding responding to your message to prevent potential conflicts or emotional turmoil.
Respecting Boundaries: He could be setting boundaries for himself after the breakup and chooses not to respond to avoid reopening old wounds.
Unsure How to Respond: He might be unsure how to respond to your message or is taking time to think about what to say.
Lost Interest: It's possible that he has lost interest in communicating with you or doesn't see a reason to respond.
Remember, everyone handles breakups differently, and his response (or lack thereof) might not necessarily be a reflection of his feelings towards you. If he initiated the breakup, he might have already processed his emotions and moved on. It's essential to respect his choice if he doesn't want to engage in communication.
If you're looking for closure or hoping to rekindle the connection, it may be helpful to seek support from friends, family, or a therapist to process your feelings and emotions about the situation. Focus on your own well-being and personal growth, and remember that sometimes, a lack of response can be a clear message in itself.
