BOK, (read this!!!)
I'm not going to tell you that she's faithful,
BUT,
My wife had a lot of trust issues with me, and was independant as hell.
She do things like go out with friends and say the same things, just because,
"it shouldn't matter to me"
I've never doubted she was faithful,
but you're right,
she should want you to be more involved in her life,
and eventually it will come,
express yourself honestly,
and good luck.
