Is what the girl did—lying, deception, and exploitation—considered injustice?

What is known as a love relationship between young men and women is not sanctioned by Islamic law. The religiously permissible way is for a man to propose to a woman through her guardian, and she remains a stranger to him until the marriage contract is concluded. Lying and deception are forbidden. By engaging in these actions, the girl has first wronged herself by entering into the relationship, and you are her partner in that wrongdoing. Therefore, you must repent to Allah by ending the relationship, regretting your actions, and resolving not to return to them. Marrying a religious woman is in accordance with the recommendation of the Prophet, peace be upon him.
