All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad is His Slave and Messenger.
First of all, you should know that what you mentioned does not affect the validity of the marriage contract, so you are still in marriage bond with your husband until divorce or Khul' takes place.
In principle, it is not permissible for a wife to ask her husband for Khul’ without a sound reason. Thawbaan said that the Prophet said: “Those who seek Khul’ are the hypocrites.” [At-Tirmithi]
If you are harmed by your husband and fear neglecting his rights, then you have the right to ask him for Khul’ in return for compensation that you pay to him. For more benefit on the rulings of Khul’, please refer to Fatwa 89039.
However, we do not advise you to rush to ask for Khul’ until you make sure that this is the best solution for you. Since that man expressed his love for you, you should try to reach a mutual understanding with him so that you can solve your problems. It should be noted that the wife has the right to be in a separate accommodation away from the husband's family. For more benefit, please refer to Fatwa 84608.
If you do not reach a solution, and after having waited and consulted others and performed the Istikhaarah prayer, you believe that it is most likely that the best solution is separation, then it is permissible for you to ask for Khul’, as divorce before the consummation of the marriage is better than divorce after its consummation.
Finally, if you have probable cause to believe that you are affected by an evil eye or magic or the like, then you should both perform the Islamic Ruqyah and ask Allaah to heal you. For more benefit on how to treat evil eye and envy, please refer to Fataawa 89017, 83898.
Allaah Knows best.
