Husband refusing to issue talaaq

Q: I am a mother of 4 and have communicated with a Moulana that I would like my Talaq due to a toxic and unhealthy relationship. He refuses to give me talaq and I am now considering leaving. If I leave, how long does it take for an automatic talaq to be finalised and if not how may I, as a woman, go about giving him the talaq.

Marital problems

Q:

1. I am a 30 year old married woman. It is 7 years since I am married. There has been marriage issues between us. Now he decided to divorce me. We have a 5 year old daughter. But I dont like to get divorced as it is a major sin. If he does so, is there any sin on me?

2. Also, can you send a dua to me to avoid a divorce. I am very depressed.

Talaaq on WhatsApp

Q: I was recently married and have asked my husband for talaq because he is not providing for me and since I told him I'm pregnant he has not supported me or the baby, he is not with me cause he chose to walk out on us, he cannot provide a home or anything neither has he done anything as far as the pregnancy goes, I am doing this on my own but with support from my family. He did give me talaq but via watsapp, so I would like to know if the talaq is valid?

Buying back an item at a lower price

Q: I am in the business of buying and selling car mags. A few months back, I sold a set of rims to someone for R1800. A couple of months later, I got a call from the same person asking if I want to buy these same rims back because he had no use for them. I made him an offer of R1200 and purchased them back. Is this considered as riba or is it permissible?

Choosing a spouse

Q: There is a girl I really like so I told my parents about her and finally my parents met her family. Now the situation was to take the final call. I asked my parents about their opinion and they said that since they met the girl and her family just once they might not know much about her and they asked me to take a decision. They also said that they are neither opposing her nor forcing me to marry her but they mentioned one point saying that I might get a better girl considering the fact that the girl and her family has little less knowledge and teachings of Islam and they also said that they wouldn't have preferred the girl. But again they said that they are OK with the girl if I select to go with her. So I am really confused right now. I dont want to hurt my parents and I dont know if they get hurt if I decided to go with this girl. Please help me.
