Answer :

In the Name of Allah, the Most Gracious, the Most Merciful.
As-salāmu ‘alaykum wa-rahmatullāhi wa-barakātuh.
We understand the crisis you are in and we sympathize and make duaa for you. It is noteworthy that you have changed your life and we pray that you remain steadfast on it.
On the outset you have been married for the past seven years and you state that the relationship was good between the two of you. She would take good care of you and your parents would love her like a daughter. You also state that the last time you met was three months back and she is also willing to meet you but her mother refused.
Whilst the possibility of black magic cannot be ruled out, there may be a reason for her mother wanting to break off the relationship with you.
We advise that you identify someone who has influence on her mother to intervene and identify and eventually solve the problems. Continue praying unto Allah to soften her heart and for the return of the blissful married life. It would be advised that you devise a plan to live together even though you both are still studying.
