Husband not fulfilling the rights of his wife by living in another city

Q: I have a few questions regarding my married life

1. If a wife cant do anything without the permission of her husband then whats the difference between a slave and a wife. If a wife cant have permission to study for a job or she is begging her husband to give her permission to see her father or relatives, however her husband is not living with his wife. He is working in another city and his wife is living with her in-laws. 

2. My husband is working in another city. He comes home once a month. I'm living with my in laws; my father in law, mother in-law, my two single brother in laws and two single sister in laws. Its been three years since my husband is working like this. We have two kids. Whenever I ask my husband to come stay with us forever, he says that he cant because this is his job and he cannot find another job there. He fights with me that I musnt tell him every time to leave his job coz if his rizq is there then till the time Allah has written his rizq there he can't come. Im very sad and cant live without my husband anymore. If I ask my husband to come and live with us is it permissible for me? I married to him to live like a family with him not alone.

Words of talaaq used in different areas

Q: I recently got married. I live abroad and my husband is in Pakistan. One day my husband was angry and said that agar tum Pakistan na ai to meri taraf se azad ho jo marzi kro. When he was calm I asked him what he meant from the word "azad". He said that he didn't mean it as divorce but used it as he wounldn't care about what I do and I am free to do whatever I want and he won't care. He said the word "azad" once. I wanted to know if it's condtional divorce? And what if i don't go to Pakistan will it be considered as one divorce? He assured me that he didn't use the word azad fot talaq but I read somewhere that if the husband says the word azad while he is angry then there is no need to ask about his intention as he meant it as divorce thats why I am worried. And if I go to Pakistan then would it still be consisdered as divorce? One last thing is that I have to come back to Denmark every six months because of my papers. So I asked him when he was calm if he meant that if this time I won't come then I am free or every time I have to go back to Pakistan? He said he meant it this time and not for future. I hope you understand my question and can answer me as I am really confused if I should go to Pakistan or not?

Providing for one's father's new wife and her children

Q: My father has married a young woman who has brought three young children with her and a grandson. My father does not work and he is almost seventy now. He has no pension whatsoever and his only source of income is the money me and my siblings give him. This is his third marriage. The first was to mother who passed away, he got divorced in the second marriage and he was living with my elder sister until now. Then he got married and decided to move into the unfinished house we were building for him. The question is, me and my siblings do not have well paying jobs and still we tried our best to care for him but now he has brought a woman and 4 children that will need support from him. As a Muslim, is it my duty to care for his family? It was already hard to care for him alone and just how are we going to manage taking care of 6 people including him and his wife? Will Allah Ta'ala be angry with us? Because when we send him money now its never enough and we also have our own lives to care for.

Separation and faskh

Q: Me and my wife are currently separated but not divorced. We have been separated for 6 weeks now. My questionson are as follows

1. How long are we allowed to be separated before our marriage is null and void?

2. My wife wants a fasagh however I want to reconcile. The problem was that I borrowed money from a friend and never told my wife and she only found out afterwards that I borrowed money from a female...is she allowed to be granted a fasagh on the basis of mistrust and lies?

3. If she insists for a fasagh and I dont want to because I still love her and for the sake of the children, can the Alim force her to give me a chance even though her parents don't want her to take me back?
