Riba and divorce

Salam w aleikom, Dear brothers and sisters,

I am seeking urgent advice in regards to two situations;

1.- I am working in Spain and living with my mother. My salary is very low and the rents are very hight. In order to rent a flat I am forced to share with other people, right now we rented a room to a respectful gentleman, but still is very complicated to share even with women nowadays, as I had bad experience with that. For a normal flat the price is aprox 800 eur plus expenses and my salary is 1000 eur. The question is related to RIBA, as there is an option to buy the same kind of apartment with a fixed interest nowing the final cost of the apartment at the final payment and the monthly payment to the bank is 380 eur per month. So renting is 800 and a property 380. Is this posible or it is haram?

2.- The second question is related to my husband. I married to a gentleman who told me and my mum he was divorced with 2 kids from a woman and one son from the first. After I got pregnant I found out that he was not divorced from the second wife, even though they didnt see each other for 4 years as they were only talking over the phone. That woman started threatening me, there is no way to comunicate with her as she became atheist even if originally she is moroccan. She threatens me qith Sihr and even with killing me. So my husband and I always had problems, we love each other but there is something that attaches him to her. I had a miscarriage and after I got pregnant without planning it. In march 2016 my husband was gonna travel because he always tries to find a way to talk to her and others and to make money to help them, I told him I had a primonition that he was gonna go to prison. He didnt listen to me, but after a week he was jailed for a transaction that went wrong. I was 3 months pregnant and even if he had a 3 years judgement i decided to stand by him. Only allah knows what i have been through, alhamdulilah 3ala kuli hal. His other wife made my life like hell. The day my daughter was gonna be born she died due to no reason as doctors said. Inna li lah wa inna ilaihi raji3on. Now He still calls me from time to time saying he will come to me but as well I know he stills talk to her and she expects him to be with her as he is coming out from prison in 3 or 4 months inchaalah. I am suffering a lot, my mother is scared from the other wife because she promised she will find a way to kill me.
My husband use to live like a kafir nd my condition w to stay with him was to come back to Allah and pray, so he did and that made me believe I could trust him.
I love him a lot, proof of that is that he is 24 years older than me, but also im scared from the other person as she has no rahma on her heart and I dont know what is on his mind. So, brother or sister, please guive me an advice. Jazakom lah khair, salam.

Dear, Sarasaida. I can only answer the first question and give my opinion on this topic. And I think you have the right to do what you want to provide for yourself and your family, and I don't see anything wrong with that. Oh, this's an old post. I hope you've already solved your family and financial problems. By the way, if I have any questions about my marriage, I consult with a specialist or read various articles about how to save my marriage. But I admit that we sometimes have serious problems, so we are close to divorce. However, I will try to do everything possible to save the marriage, because it will be very difficult for me to raise 4 children alone.
