What is the religious ruling regarding someone who pledged three times before God and then kissed me, only for it to become clear that he is married?

The questioner has transgressed Allah’s boundaries by engaging in an unlawful private meeting (khalwa) with a non-mahram man, speaking to him with softness and submission, and then by touching and kissing. Satan is luring her to what is further, unless she repents. The Prophet, peace and blessings be upon him, said: "No man is alone with a woman but the third of them is Satan." And Allah Almighty says: "So do not be soft in speech [to men], lest he in whose heart is disease should covet." This type of man is not trustworthy; they exploit the naivety of girls and then disavow them.

It is obligatory for her to hasten to repent and cut off her relationship with this man, and to adhere to the laws of Allah and the hijab of the Muslim girl. Allah provides for whoever fears Him and eases his affairs.
