Breaking up a marriage

Q: If you see the signs of the curse of Allah Ta'ala on someone where they are unable to make duaa and you know he isn't a good person but hides it and pretends, what do the teachings say in breaking up his marriage and removing the wife from this ordeal?

Saying "nikaah khalas" intending that one is married

Q: I am in Saudi Arabia and don’t know Arabic. One day I was talking to a person who didn’t understand much English. He asked me whether I am married or not. I said to him "Yes, I am married" but as he was weak in English so I tend to speak Arabic and I said “nikah khalas”. I found out khalas has many meanings in Arabic such as done/finish/over/complete. But my intention was to say nikah is done/hogaya so will “nikah khalas”  be a word of talaaq or not?

Repenting from illicit relationships

Q: I had love affairs and also fulfilled sexual desires with the girls I had affairs with. But then I got married and have 2 kids. Now I think that if I do it or go for non means, I will be punished in the form of my children doing it. So please give me a solution to the problem. If I marry someone, my parents and my wife's parents will be against me.

Seeing a coloured discharge three days before one's haidh

Q: It was the time of my period and I got a peach discharge, it wasn't a dark peach. So I asked my teacher and she said that it is my period. (I don’t get any colour discharge during my tuhur period). so I took it as my period, I never discharged more of this colour, I discharged clear and white. I only started bleeding 3 days after I saw the peach discharge. Please advise whether the 3 days in which I saw nothing was actually my period, or did my period only start when I started bleeding. This happened during Ramadhaan.
