How can one reconcile an emotional relationship that has lasted for four years, which began before and is affecting university studies, with maintaining the great trust placed by parents, knowing that hearts are in the hands of Allah and that the love of Allah is higher and more important?

Conversation or correspondence between a man and a foreign woman is a gateway to temptation and a means to corruption. The relationship of love between young men and women is not sanctioned by the Sharia and leads to infatuation, which corrupts hearts. You must immediately sever your relationship with this young man and divert your heart from attachment to him. If he is serious about marriage, let him propose to your family. Otherwise, occupy yourself with what benefits you until Allah blesses you with a righteous husband.
