How can I proof my love marriage without photos

Hi, I was in relationship with my lover since 2012. Then we got married in a temple witness of temple priests and workers on 28-feb-17. But we didn't register it. Both of our parents was not aware of that. Later my wife inform to her parents that she is in relationship with me and want to marry me with their permission. She didn't tell them that we got married already. So her parents are not ready to allow her to marry me in front of all or they are not allowing to live with me. They stopped all contacts between us by house arresting me. When I contacted her brothers they are not receiving the calls. So that, I have applied for restitution of conjual rights. But I have only our marriage invitation and the priest given letter mentioning that he had done our marriage as proof of our marriage. I don't have our marriage photos. The photos taken on my wife cell and she only kept them with her. My friends and priests who were attended my marriage are ready to witness. When court sent RCR to her address they rejected the notice. I thought she will receive and attend the court so that I can ask judge for councillor to us.. Please help how can I deal this case. Is the marriage invitation, priest letter and eye witnesses can consider as married proof in court in the absence of my wife. And also I have chat conversation of my wife, there is conversation about our between us. Is this considered as proof in the court. The messaged is on her name only but how can I proof it in court because it’s civil case, if it is criminal case police can give CDR details but here it’s not possible so please help me to get this case.
