Can we stay together despite wife’s separation request and my talaq under parental pressure?

I and my wife were leading happy life. She is Muslim but not religious and do not know about khula and talaq. She is from poor family. I made a wish to turn and make her to learn basics of Islam and slowly she was turning and was performing namaz and reading hadith because of her arrogant nature and quarrel between us she asked that she want to get separated. Initially I said her “aap ko agar jana hain to ja sakte main jabar dasti nahi karoo ga muhje toh aap ke sath hi rehna hain” after some days, she was pregnant about one month and sudden miscarriage happen and after that for ten or more days she was at her mother place, then with my parents and I went her home. We were not in contact neither phone nor SMS. My parents asked her to come home she replied no then my parents asked do you want to get separated, she replied yes. But we do not want to get separated. We both were scared of our parents. They made khula bond papers and made me to give talaq to her. I said what I should say my dad said me “you say afrin aap muhje khula maagre aur main aap ko talaaq de deta/diya” then I was repeating my dad words which I do not want to give just I uttered because of scared and afraid of elders. And they made me to say the above sentence thrice which I uttered followed by my dad words. On the same day we sent all her belongings and gifted things at her home. The very next morning she met me and said I want to live and stay with you. Even I am ready to accept her. Please show us the right path.
