I have done zina with this man I love for the past few years that I have been seeing him. We decided many times to stop this act by repenting and not committing it again however we keep repeating the same mistakes again. its been 4 months now that we have stopped, and I am hoping to not commit it ever again before marriage.However, we have family barriers that would not allow us to get married and hence, we thought that the best way of seeing each other without causing anymore sin is to marry each other. I do not mean any disrespect to both our parents, I love them very much but this man is whom i want to be with for the rest of my life. I want to nikkah with him as soon as possible. How is this possible? Forgive me for my rudeness.
Go to an imam that you trust and ask him to act as your wali before two witnesses and to formalize your nikah.
