But, if you want our opinions, people's opinions, then my opinion is I reckon he is cheating, and this is coming from a guy. Cos I did similar shit when I was younger, and it was cos I was cheating, I was chatting to other girls and shit. If he's being that defensive and secretive about female friendships he has, then it's clearly obvious. Think about if the roles were the other way round, if it was a female with guys, guys would think the same about the girl.
