Three talaaqs

Q: I am married to my husband on 15 July 2009. After four years he say divorce to me twice in one setting then my family said we make this home again and you will ruju with him. 

I am OK and and we start life again. Last year he again divorce me three times in one setting. My family contacted mufti and told him the whole situation. He say there is a gap in wordings and this is the last chance to continue with him and ruju. 

Now this year on 5 Jan, he again say divorce three time in one setting. Now my heart say something is against the laws of Allah. Please give me your option not live with him. He again say I am not mean it.

Husband not taking care of the needs and expenses of his wife and children

Q: I am a working woman and married. Both me and my husband are working in respectable jobs. I handle my own personal expenses from day one of marriage and have never asked for pocket money from my husband. 

I have two children aged 1 year and 1 month. My husband refuses to help in the my children's financial needs. Both of them are on formula milk and their combined expenditure is around 80000 which I am solely bearing along with my own expenses. 

My husband's income is more than me. He refuses to contribute even half. Alhamdulillah, I am managing but my question is what are the rights of such a husband/father over his wife and children if he refuses to contribute even 50 percent financially if he has more than enough money. What are the faraiz and instructions for the mother/wife in such a case who despite being married is living like a single mother?

Explaining the serious consequences of uttering the words of divorce to one's wife

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.
