Marital problems

Q: I got married when I was 21, and my husband was 36. When we met he was a non-Muslim, but reverted to Islam a month before we married. We have now been together for 14 years and have 3 Masha'Allah children. When we married, I did not practice Islam, or wear Hijab. About 2 years ago I realised that I had to make a change immediately and started wearing Hijab, making Salaah, and educating myself and my children on Islam. My husband was never interested. He always has an excuse, and has now even stopped going to Friday prayers. This is a huge concern for me as I worry about the example he is setting for our children. Whenever I try to speak to him about this, he laughs and says that I worry about everything. I've asked my father for help but he told me that I need to sort out my own problems. My husband has never had a fulltime job in all the years that we have been together. This means that I have to provide for him and our children (home, food, schools, transport, health, etc.) I earn a decent salary and I am able to provide for them but I'm exhausted all the time. Because when I get home from a full day's work, I still have to cook, see to the children, check that everything is prepared for the next day, clean, etc. There is almost no communication between us as we disagree on almost everything. I need to understand what my options are. I know that divorce is frowned upon, but I don't want to be married to a man who has no interest in Islam, or in me. What should I do?

Refusing a proposal due to concerns regarding the family's chastity and modesty

Q: Would it be wise to marry my first cousin whose sister got divorced but his family sent her back with her ex-husband (who actually orally gave her talaaq 3 times) knowing the ex-husband had given his sister divorce? She is now living with her ex-husband and his family. Thus frustrates me and her brother has asked for my proposal. 

Travelling safar distance

Q: If I intend to travel to a place which is more than 50 miles away (Place A), and intend to stay there for 20 days, I understand that I will not be a traveler and will not do qasr. However, after 20 days at Place A, if I travel to Place B which is 50 miles away from Place A, and intend on staying there for 5 days, will I do qasr in Place B?
