Reuniting after khula'
Q: My wife got a separation from me through court and that is khula. No divorce word is mentioned. I did not take mahar amount from her. She also took my 3 million rupees and did not give me back at that time and not yet even. I love her and we have 2 daughters. Khula is done on 8th January 2018. I am giving her all amount of her expenses also. After two months we had intercourse with an intention to live together again and I promised her that nothing will go wrong by the grace of Allah. Is her khula valid after all this? What do I do to bring her back?
