Wife giving preference to her madrasah work over her husband

Q: Alhamdulilah, I am happily married, however I require clarification over a matter.

I work from 8 - 5 and my wife teaches hifz in the morning and madrasah in the afternoon. She is occupied and very busy the entire day. I have no problem with her busy day and am happy to let her serve the deen of Allah Ta'ala.

However during the evenings she does not provide me with her full attention but is still busy dealing with other work. She gives off the impression that her work is more important than me and often compares myself to her.

Am I correct in telling that her I am her primary responsibility and take preference over everything else?

Non-Muslim brother inheriting from parents

Q: My brother has gone away from the fold of Islam by having a girlfriend who is Christian Orthodox, committing zina, having a child out of wedlock and then saying that he will be become Christian for the sake of his child and girlfriend. He contacts my parents only when he wants some financial help otherwise he is not in contact with them or other family members on any regular basis. Whenever he does contact my family, we have always tried to remind him of Islam and Allah.

1. What does Shariah say for this matter with regards to his inheritance from my parents when they pass?

2. Should he be included in any will my parents make?

3. Does he have any right to claim inheritance from my parents if he is no longer Muslim?

4. Does my family have any responsibility or rights towards my brother if he claims to have forsaken Islam?

5. Should my family maintain contact with him or do we sever ties with him if he is no longer Muslim?
