Stranger can see my texts on iMessage?

[Anna]

It may be fake. But as a precaution becareful what you text

This really should not be possible. When you text someone, you are sending a message directly from you to them. No one should be reading it in between. You may have accidentally added someone into a group conversation, or your friend on the receiving end could have shown the conversation to someone. But other than these little things, there should be no reason this is possible.

Just be careful and watch who you're sending your messages to.

Most likely just a hoax, but there is actually a way.
If one person has imessage on their phone, and another person (on an ipod or ipad, wouldn't work with a second iphone) used their number and/or apple account via email address, they could potentially see all the messages you've sent since them joining. If possible, i suggest you change the password to your apple account, deactivate imessage then reactivate. That should stop them seeing anything you send.
