You can’t be cold hearted while having fond memories. Delete all texts, emails, etc. Rid yourself of pictures, gifts, and anything else that reminds you of them. Even if you did have some good times, your memories of these must be sacrificed in order to make the clean break from this person.
When you call a dead phone does it ring?
Answer: A: With a dead battery it should not ring but it should go to voicemail directly.
