Help! My brother's wife is tearing him apart

Please I need you to help me post this so my brother can read people's comments on it . My brother's marriage is 5 years and he is still a salary earner. He earns 80k and he drives his keke weekends to patch up but during the week , he gives it out to a man who makes returns every Friday for him . He has a son and now his wife is pregnant with the second child.

Recently his mother inlaw passed on last year December and since this woman died, my brothers ass has been on fire. His wife started making unnecessary demands. That my brother should know she is the Ada. Her mother's Ada, that my brother will have to prove himself he is a worthy inlaw. That my brother is meant to contribute to her mother's burial arrangements so her people won't look down on her. That my brother should look for 200 -300,000 and send to her people to show support, then after that, he will buy life cow he will use to come for the burial.

My brother ran to me to borrow money, I asked him why , what for? He said his mother inlaw burial expenses is eating his pocket down. The burial is coming up last week of February. He payed his house rent 245,000 this January. He has made a hospital deposit for his wife's delivery because she will put to bed first week of April. The lady is demanding for a new baby cot as well. This is a lady who knows her husbands pocket isn't that deep. She keeps threatening my brother to better not disappoint her on her mother's burial. I have told my brother that I won't give him any money, that if he can't go home and caution his wife, he will have a very big problem with her demands at the long run.

This is a boy I raised when our mother died because he never knew who our dad was . My father died when he was 5months old. The only son of our parents. I was the person who took out 800k from my business and funded his traditional marriage and white wedding. I needed him to marry early, but he married at 30 years. When my mother passed on. My marriage was 8 years old. My husband was a factory worker. He did his best and I didn't nag him. He was even feeling he let me down. 15 years of our marriage, he gave me a million Naira cheque and asked me to please add the money to my business, that he wish we were this comfortable when my mother died. I was the one that payed two years house rent for my brother, furnished his apartment before his wedding. I was shocked when he told me that his father inlaw called him to ask him of money, he has sent him 100k second week of January. What he came to ask me for was 500k to run the burial expenses of his mother inlaw. I was like, are you mad?

He said his inlaw is asking him of his own contributions and his wife is giving him pressure. I told him that 100k is enough, he should tell him so. That what he needs to do now is to prepare himself and attend the burial holding (Ogbuli ehi) cow rope and 50k cash in an envelope, that I will buy 4 ankara he can throw at his wife while she dances around. That I won't give him any money. I don't want to speak to his wife because I am a very hot tempered fellow, I might blow things out of proportion your friends should advise him for me please, I have asked him to follow you up on Facebook yesterday.
