Wife not practising Islam

Q: I want to ask if a man embraced Islam for almost 13 years and his wife also and children embraced but his wife and children don't want to perform salah and other obligations of a Islam. His childrena ages are 20 years and above. What should he do? Is it right to divorce her?

Wearing suede shoes

Q: This might sound like an odd question but I was looking at some shoes and read that they were made off suede. I know that wearing pigskin is not permissible so I emailed the company that was making them (Louboutins) and they replied with saying that none of their shoes were made of pigskin but I am still wondering if I am able to wear them.

Breaking a qadha fast

Q: I know that we can break a nafl fast if there is an 'uzr (excuse). For myself as a diabetic, I assume that an 'uzr could be when I get very low blood sugar values which makes life difficult for me if I don't eat.

1. Is it also permissible to break a qada fast if you have an uzr?

2. If so, would you have to make one or two qadas? (i.e. do you have to make up the original fast as well as the qada fast that you broke, or only the original fast?)

Reading novels

Q: I would like to know whether or not it is permissible to read books which make you think of unnecessary/evil images. I am a practising Muslim, however I was enjoying the book 'thirteen reasons why' until I felt I needed to ask.
