My boyfriend acts different at school . Why ?

My boyfriend and i go to different schools and we usually get along great. Today, we were hanging around in his room and i saw his school's year book so i started to flip through it. (my boyfriend was in the bathroom at this time) . Then i saw a girl's handwriting in the autograph section so i started to read and my boyfriend walked in and he took the yearbook from me and told me not to look at it. I asked him if he was hiding anything and he said no. After arguing with him for a while he let me see it . I flipped back to the autographs section to read the girl's message and it said " you are the funniest, coolest, sexiest guy i have ever met (when you are not a perv) " (i got pretty pissed) and i read some other messages and they were along the same lines as the first message. Then, i decided to look at some of his pictures and the first picture i flip to, he was sitting on a girl . (wtf isnt it supposed to be the other way around ?) well anyways, i confronted him about the picture .

and he said that it was from the beginning of freshmen year ( we are sophomores now) when we weren't dating. Should i be worried?

Well you shouldn't be worried about him cheating on you, but he sounds like a player/pervert which may worry you. He probably hangs out with the type that act like idiots, which make him act this way. Either go visit him at school and launch a kick between the legs, or go let him be.

He's a player.
Don't you want more than that?

Don't worry about it's a man thing he will get over it

i don't know.
i kind of would be, cause that's pretty weird behavior for just looking at his yearbook. It's pretty suspicous to me if he gets all weird from u looking just reading what this girl wrote him.
