To prove that the marriage was not consummated and the wife didnt live together even for a day

Greetings. I married my aunt's daughter on 29/4/16.She came to my home after marriage and left my home just before first night and alleged harassment by my family due to which the marriage was never consummated. With the support of my relatives, for more than two years, She and her family never gave access to us to discuss or reunite despite we sending many people proposing to sort out. So, I petitioned the Court to grant me divorce on grounds of non consummation and desertion. She has filed a counter that the marriage was consummated and she lived with me for two months initially and from then she shifted to parents' home where she alleged that i visited her . She has falsely accused me of an extramarital relationship, dowry, mental and physical harassment by me and my family during her two month stay at my home and thereafter as well and alleged that she has given me 45lakh dowry and 80 sovereins of gold which is false as i took nothing from them and I bore the wedding expenses. Kindly opine as to how to proceed. Thanks in advance
