I'm involved in Haram Relationship, I asked for forgiveness and she isn't forgiving me. I don't know if I'm guilty or not, I just want to end this relationship and ask Allah for repentance and forgiveness. I don't want to continue this.
I have guilt that if she won't forgive me so I won't be forgiven on the day of Judgement. Is this true? Please enlighten me with your wisdom on this topic. I'm very ashamed of myself and I just want to keep myself away from all haram deeds.
The first step of Tawba is feeling guilty about your sin. You must acknowledge the sin and feel ashamed of it and to stop the sin immediately and make resolve not to return to it. If you had harmed someone then you need to seek their forgiveness. This is sincere Tawba.
As you have tried to seek forgiveness and your wife is not forgiving. Have hope that Allah will forgive you, inshaAllah.
Remember, Allah forgives in abundance and very Merciful.
"(And remember that) Allah's acceptance of repentance is only for those who commit evil out of ignorance and then soon repent. It is towards such persons that Allah turns graciously. Allah is All-Knowing, All-Wise." (Sura Nisa 4:17)
