what happened to my facebook message?

[Rach]

I was talking to this guy on facebook and the last message i sent to him he didnt see. So the next morning about 8am i went on the message and he still didnt see it. Around 1:30 i check again and it said seen at 7:18 but at 8am it wasnt seen so at 7:18 did he click on it and unseen it and a few hours later click back on my message so it came up with the time when he first seen it?

he read it, and then marked it as unread so that you wouldnt know he read it....
