I'am 16 years old girl, I'm in love with a respectful man whom the relationship is being restricted to that exchange especially after my mother had come to know so I didn't know how to carry on with him upon that restriction which had me to get in touch with a psychiatrist thru Facebook. I revealed to him my issue then he deduced that my femininity is overwhelming which was making me go thru a sexual deprivation then he persuaded me to ventilate my desires thru sexual tchat, to the point of sending pornographic pictures to stimulate me and asking me to do alike, arguing that it was a petty sin and it was compulsory to satisfy my own sexual needs. I've sunk into that sexual pattern until I woke up from that shameful behavior and realized how sinful I have been so I decided to cut off with that and break up with him. He insisted that we should stay together or at least remain friends but I refused and blocked his contact. Ever since, I have been troubled with remorse and regrets should my fiancé know or any one else but mostly how dare I could get involved into that practice, I can not help fearing Allah's punishment , being torn apart with his reprimand of revealing my sin to my fiancé in the day of judgement as well as the persistent concern that he shall not forgive me though I keep praying and praising his almighty to forgive me, on the other hand I do not whether should he forgive me he will help me to forget what happened and move on. I'am so troubled with the idea of betraying my fiancé especially that hi is a very serious and respectful person and will soon marry me. Please advice me
