Hello mochit, and welcome to a2k
Well, there are two issues here. First, why did you marry your wife,
if you don't agree with her being an MTV girl, superficial and rebellious.
Whatever attracted you to her, is what she is. It's not fair that you're
trying to change her now, after you're married, because she all of a
sudden doesn't fit your lifestyle any longer. Let her be who she is,
and she'll thank you for it.
Secondly, having racy pictures done with her ex-boyfriend is not
necessarily something I would endorse either, however, I have a feeling
that she's just testing you, resp. is upset over your behavior to change
her.
There is nothing wrong with having an independent spouse, on the
contrary, it makes your marriage more interesting. You married her
because she was different than you, now you have to live with it.
It is not her fault that you changed your mind.
