Is marrying the man with whom you committed a sin the solution for psychological comfort after repentance, or will staying away from marriage and commitment restore your status as the deceased's wife in Paradise?

One must repent from forbidden relationships by feeling remorse, desisting, and resolving not to return to them, while maintaining discretion, increasing good deeds, and cutting off ties with the man. If a man of religious commitment and good character proposes, and you fear falling into the forbidden by refusing marriage, then you must accept him. Sincere repentance erases sins, "The one who repents from sin is like one who has no sin."
