I have had this happen twice and Apple IDs are not shared. It happens only with messages between my daughter and me. My daughter’s phone ends up being merged with a commercial vendor and I get spammed with “we can’t reply” messages. The fix to delete the conversation works but deleting all my texts (even if backed up) is a terrible workaround.
