Husband cheating on me how can I prove in court

I’ve been living with my husband from 13 yrs and married frm last 3 yrs. Recently I discovered that my husband has been cheating on me with multiple girls and prostitutes from the very beginning of our relationship. We belong to different religions and had a civil marriage since we didn't want to convert (I am a Hindu and he is Muslim). He admitted to cheating on me. I have screenshots of his chats with his friends bragging about these affairs, some of the flirtatious msg exchanges with girls, and contacts of prostitutes saved on his phone. Will these be sufficient proof?
