Getting involved with a married woman

Q: I am involved with one woman. She is the mother of 3 kids and she got a husband as well. I am trying to get rid off her but I can't control myself. We are working in the same place. It is not that I love her but if I don't talk to her, I feel strange. I feel very disturbed. She always ignores me. She always hurts me. She never values my feelings. She sleep with her husband as well I know. But she never admits it. I want to go away from her. But
I can't change my job. She works there. She treats me as a slave. Whenever she feels, she talk otherwise no. I just want not to even think about her. Please tell me something.

Life insurance

Q: Is it permissible to use Life insurance or medical insurance by LIC (which is run by the Government of India) like we use other benefits which the Government provides (e.g: Government provides money to people who are injured in an accident or for treatment. etc)

Going to work in iddat

Q: May Allah reward you for the good work you provide for our ummah. My question is if a wifes husband passes away does she have to complete her iddat on the excuse of saving her job? The husband has left an amount of R130 000 in the bank account. Wife has about R100 000 in her account. Wifes father Alhamdulilah is quite wealthy and he only has two daughters. All in the family are working and earning. Its a government job. Sshe has the fear that if she stays on for her husbands iddat there "might" be a risk of losing her job. We do know that south africa is a freedom of religion country. We do know that if she does not go to work, there will be enough to take care of her needs in the four months of iddat. If she stays in after looking at all this is she still allowed to leave her iddat for her job?

Doubts in Surah Faatiha

Q: In my 'Asr Salaah I recited a verse of Surah Faatihah and whilst reciting I thought I made a mistake, and thought I'd repeat that verse and I didn't
stop reciting until I finished the verse, and then I recited again, but during the verse in which I thought I made a mistake, I was like “Shouldn't I stop?" But I carried on until finishing that verse; now I wonder, does this count as a purpose addition in prayer by finishing the verse in which I thought to have made a mistake? And is my Salaah valid?
