Marital problems

Q: I have two wives, my first wife is here with me and second wife is abroad. My first wife has not come to terms with my second marriage. Instead of paying attention to her house and children, she was always prying about what im sending to my second wife and when I contact her. I had many times told her, that do not think of that, it is not your concern. Just concentrate on home here and children. But she went on it on and off, resulting in irritating me. I started to leave the room when she started so that the matter should cool off, as per instruction of my mother. But the last time i did that..my first wife followed me and misbehaved with me with strict words and i retaliated back. After that she has separated her room. I am being normal with her but she is persisting in her attitude, my mother has tried to tell her, this is not doing any good to home or children, but her answer is i have cut of all contact with him (me). I will just give him food etc. other than that i have no relation with him. I am not forcing or anything now. Just complying with whatever she is doing. Please advise

Restoring one's Imaan

Q: All my life I had been a Muslim but recently I began to watch videos on athiesm. At first I didn't believe them but now they have destroyed my iman. I begin to think why would Allah need to create humans and why does Allah not just show Himself? If humanity was created to perfection, why is there so much pain in the world and lastly why is there no clear proof. Please I want to restore my faith I feel so lost.

Wife demanding exorbitant amount for divorce

Q: I took a second wife while I was still married to my first wife because my first wife had an issue called vaginism as she cant have sexual intercourse. After 2 months my 2nd wife started to behave wiered as she seems to be going through some psycological issue in her life. She tried to commit suicide more than 5 times while she was with me. Now she is asking for 5 million for me to give her divorce. I dont have that much of money to give her. I was paying almost 3 year close to 1000 usd every month just for her and the son she got from her ex husbond. She was kicked out from her parents home. Now she is troubling me asking me for this large sum of money for divorce. Am I allowed to take money as a loan from the bank to pay her and release her from my life to live a peaceful life
