Kind of like how you hide the side of you that makes fun of nerds on the internet from your GF. It's like a betrayal of trust.
While telling her would have been open and honest, people have the right to a degree of privacy, and not allowing him to have this is lack of trust.
It is not him being untrustworthy, it's that she just doesn't trust him.
I firmly believe this situation in no way reflects on him and does reflect entirely on her own insecurities.
