Informing the wife of one's return

Q: Is it obligatory for the husband to inform his wife before he returns home or can he return unexpectedly, without informing her? Will there be a difference in the ruling in the case where the husband was gone for just a few hours, and the case where he was gone for a prolonged period? Also, is there any Hadith in this regard?

Living away from one's husband

Q: I am married to a man whose hometown is 200km away from mine. He was working abroad so he promised me not to separate me from my parents before our marriage. Now he came back to our country and started a business. He stays at his home. But I still stay with my parents as they are old and sick. I am their only daughter. They don't want to let me go to my husband. I am a teacher so, I go to my husband's house only on Saturdays and Sundays. We are married for 3 years and don't have children yet. Is it good to stay away from my husband as I need to look after my parents? Is it permissible?
