Woman extorting money from husband after khula

Q: My (ex) wife asked for khula to whom I provided for 14 years as per my duties. I have never been abusive to her. I agreed to providing accommodation (3 bedroom house) and maintenance as asked of me under sharia until the youngest kid is 23 years old of my 2 kids.

My ex isn't happy with sharia solutions, avoids going to scholars and taking me to British court for my assets (£550k). She wants a permanent house in her name + extra money and putting me in much financial hardship.

What advice would you give to my wife? Would she be sinful for taking me to court after I have been sharia compliant? Would the money she gets from the court be halal for her?

Her parents are financially helping her with legal fees even though I have been sharia compliant, would they be sinful?

Women's freedom

Q: How did Islaam free the woman? I know about the whole inheritance thing right to divorce and all that. But I feel that saying Islaam freed the women is wrong because it didn’t free us. Its not freedom when your life and life decisions are controlled with your spouse or men in your family. How is that freedom? Like, I am not talking about the haraam freedom and all that. Sometimes I just wish for peace of mind sitting in a cafe that is 7 minutes away but I am not allowed to go unless my spouse feels like I can? While he can go wherever he wants whenever he wants and I am not even allowed to question him. Honestly speaking, I love my Deen so much but recently men make me get disappointed in some parts of it.
