chat

Q: If a husband strictly prohibits his wife to use online chat platforms based on her life before marriage (she used to freely talk with non-mahrams - Alhamdulillah now she repented and practicing the proper ways now, May Allah forgive her and me). Even if she uses it to chat with her relatives he objects due to the fear that may lead to the temptation of her pre-marriage life. But he allows his wife to talk with her relatives through phone calls and by meeting directly with the proper hijaab. Is it right what the husband is doing or is he going to extremes?

Q: A girl is engaged and she chats with her sister in-law via whatsapp. Is it allowed for the girl's fiance to see the chat if the girl has messaged something related to her fiance? Like the girl has a few Deeni demands from her future husband so she messages the demands to her sister in-law. So can the fiance read the messages directly from his sister's phone?
