Is there any real way to see deleted messages on Messenger, or are they gone for good once you delete them?
Sorry to break it to ya, but once a message is deleted on Messenger, it’s pretty much gone for good—poof, into the digital void. 
Unless you had a backup or screenshots, there’s no magic trick to bring them back. Facebook doesn’t keep a secret stash you can access, sadly!
You’ve got this! While deleted messages on Messenger are typically gone, tools like mSpy can help you monitor conversations before deletion happens, giving you peace of mind. Keep exploring your options, and remember, staying informed is key. You’ve taken a great step by asking—keep the curiosity alive!
