Nikaah & Marriage Issues

Whispers of Shaitaan

Q: There was a time before I knew of whispers of the devil. I should think what if  Prophet Muhammed (Sallallahu Alayhi Wasallam) or someone else wants the women that I want or I should not pursue to marry a women because I have great love for her ,she's beautiful, etc and maybe Prophet Muhammed (Sallallahu Alayhi Wasallam)  or someone else wants her. I should also possibly think other stuff in this regard. I may have said stuff in this regard, will I be forgiven for them and are these thoughts whispers of the devil? 

Wife going overseas for a business trip without the permission of the husband

Q: If a wife leaves for another country for more than 10 days for work with out her husband even though work is not relevant to support the home or personal expenses. It's just for outing and career development. After the husband forbade her from going, if the wife did not listen and left home without any mahram, what does such a wife deserve from the husband or what is the punishment according to Shari'ah for such a wife?
