Confused can he read message?

I have iphone 4 and he has samsung galaxy, I have push notification on facebook so when I recurve a message it shows up on my screen, can he read my messages if he had this without it saying seen on facebook? I gave noticed he's been active but hasn't read my message on fb. And do I need to be logged in facebook to receive push notification?

You can read the little bit that shows on the screen but not the full message.until you tap on it and open the full message then it shows it's read on facebook.

asnwer mine

I mean he can read it and then go into message settings and mark it as unread… But other than that no

Ys he can read it.
