Those situations where Talaaq does not take place

Q: When I get angry I used to say divorce me to my husband. Then to explain he said "I divorce, I divorce, I divorce. If I say these 3 words it would dissolve our marriage so don't say that again and again especially over the phone when you can't predict the other person's mental state and this can destroy our marriage, so don't ask for it again'. 

So my question is, does divorce take place by saying this because he was just explaining, without any pause, that I shouldn't ask for it again and again.

Q: If a person makes dua and in his dua, he says that he wants to divorce his wife. Is it counted as a divorce?

Q: Does nodding or a non-verbal gesture have any validity in Islamic law? Example: When he was asked about divorce , he nodded unintentionally.

Q: My husband and I had an argument on WhatsApp. He messaged me and texted that I'm leaving u from today..I'm blocking u all and said I'm breaking over the relationships. At that same moment I left the car as I was traveling and I asked him u divorce me... u using these words. He said are u mad .. did I used divorce... 

He swears to Allah he didn't intended divorce by that... He just threatening me and he just mean I will leave you but didn't leave. His sister saying she ask mufti and mufti said no divorce occur. What could I do, should I believe them?

Q: My sister, me and my husband were in a random conversation when I asked him will you divorce me. He said why not, but unintentionally. Is my talaq done? Is my marriage valid?

Q: My cousin swear to husband that if you do not follow my 2 instructions, I will be your sister. So now the issue is resolved and the instructions were not followed. Is it ok to live with the husband?

Q: One of my friends married 6 month ago. But she and her husband still not had intercourse between them. She doesn't know anything about it. Her husband also not trying to do anything. What can we do for her? How to take his feelings out? I heard if a husband and wife don't have intercourse upto 4 months, automatically it will be talaq. Is it true? 

Q: If a husband says to his wife, "If you ever tell me 'You go away' , I will go away". Is this a conditional divorce? Will talaaq occur if the wife says this statement?

Q: If someone commits kufr and they have to renew their marriage, does this count as a divorce? Have they used up one of their 3 divorces?

Q: I was married to a man in Canada and lived with him for many years. Unfortunately, we had many problems and fights, until I left him and returned to my country of Bangladesh.

My husband did not want to divorce me, so I obtained a divorce from the non-Muslim court.

A few years have passed since the court issued the divorce. I now want to reconcile with my ex-husband and remarry him.

My question is whether we need to repeat the nikaah or whether the nikaah is still intact, as the divorce was issued by the kaafir court and my husband did not want to divorce me.
