Those situations where Talaaq does not take place

Q: My parents have been together for over 20 years but have had marriage issues for a very long time. Constantly fighting and arguing. Most of the time they do not speak to each other at all and my father has left the house three times but has come back. My parents even did their nikaah a second time the last time my father came back, for fear that their nikaah had become void by their separation. Now my father has come back again, but my parents have not spoken to each other at all for nearly 2 years. They do not say salaam to each other or even look at each other, let alone speaking to each other. We have tried mending their relationship numerous times, getting the elders involved, etc, but in the end they continue to fight and argue and it never works. The only reason they are staying together is because of us. Three of us are older and understand all this, but my youngest sister is 6 and my parents don't want to divorce for the sake of their children. However my mother is extremely worried that because of the way their marriage conditions are, their nikaah is not valid and it is haraam for them to live together. So taking into consideration all that I have said, and the fact my parents have not spoke to each other or had relations for nearly 2 years, is their nikaah now invalid and is it haraam for them to live together? My father has not actually divorced my mother by saying it verbally.

Q: My husband told me 'You are not my wife, you are my girlfriend. Then I told him, why are you saying like this. Then he said 'You are my wife cum girlfriend. Does saying like this mean talaaq (the two statements above)? There was no fight or anything.

Q: Due to our daughter's illness, all our concentration were on her health as she has by birth problem. Me and my wife didn't perform any husband and wife activity since last three years as we are more worried about our daughter's condition and her health. For not performing any action of husband and wife, is there any effect on our Nikaah? All we did is mutually agreed. Please advise.

Q: If while in an argument, my husband told me to leave him alone. Is that one talaaq?

Q: Is a woman allowed to talaaq her husband? My husband doesn't care that our marriage has broken down. We haven't spoken for over 6 weeks and are now in separate rooms. Previously we have done counseling. I requested a separation. Now I have had enough. I'd rather live alone with my children then in a dead marriage.

Q: If a husband and wife argue and he tells her "pack your bags and go to your mother" and she asked if it is a divorce and he replies yes. Secondly if he says "If you can't get over, you can go" and she again asks if it's a divorce and he says take it how you want and thirdly the wife says lets get divorced and he never spoke to her correctly and just said yes without any intention. Would all three be considered talaaq?

Q: If a husband left his wife and children a year and no chances to come back to country with no money and necessary facilities and they lived alone, so according to Islam is there any relation between husband and wife remaining? He was not giving to her naan nafaqa?

Q: If the wife asked for divorce and the husband said if you bring the papers then I will give you a divorce but she doesn't get the papers does talaaq fall?

Q: I would like to know, if the wife tells you in front of the children, I am divorcing you, what are the consequences?

Q: My husband complained to my mother that"your daughter is not giving me time" out of misunderstanding. He said I cant tolerate this situation and I am fed up with this situation. My mother told him to have patience then he replied that "I am sorry I can not tolerate this." He didnt use any word of divorce at all. It was just he was complaining. He swore to Allah his only intention was to talk to me. But I am confused that can these words constitute divorce?
