The man deleted the SMS and resumed it.

After setting the blacklist, all SMS records of blacklisted contacts will be automatically classified into the spam SMS list. If you need to reset the incoming call to normal answering, you can cancel the blacklist, but the short message record will not be automatically restored to the system short message list, which requires manual operation. According to your problem description, the SMS history is automatically cleared because you uninstalled the housekeeper before recovery. If the record on your boyfriend's mobile phone has not been deleted, I suggest you use QQ synchronization assistant to back up his short message record to your mobile phone.
