Divorce Under Christian Act

Hello, I got married to a Manipuri girl in Thane Church Maharashtra, she was pregnant at the time of marriage with my child, My church is Roman catholic and she belonged to Baptist church from Manipur for which we had undergone permission from the cardinal of Mumbai Colaba with required documents too. Down the line, I came to know that she was already married in her hometown and have 3 kids from her first marriage wherein when confronted she admitted her past life and said her husband is no more, considering that it's now too late to dispute I thought of giving a second chance even after not knowing her history she gave birth to my chid in Thane Mumbai. During our relation she had an addiction to alcohol during pregnancy due to which there were daily fights as my child was in her womb, doctors advised her not to consume but still after delivery also we had issues with her same problem. Later on, her cruelty started with her ex Bf for which I was very much disturbed and disappointed with my decision and she left my son was just 11 months old and left the house staying with her community in Vashi Navi Mumbai, just after my sons 1st birthday I forgave her and bought her back to my house but still things were not going on well. After two years of his trauma finally, I came to know she used to Booz at her workplace and come home drunk at night and take my son to wine shops to buy Booz which heated things up and prior to that I caught her with my relative on the bed too due to which I asked her to leave my house immediately in anger, since than Sept 5th ( 2018 ) till date Feb 2021 I've been taking care of my Son and approaching her for divorce and for my son's custody but till now non of her family members, friends, relatives are letting me get this done. She's been changing her numbers but when called or messages I've been blocked and for 2.5 yrs I'm stressed out and wondering how to get this trash sorted out. Please help me as I haven't done any lawyer due to my work stress, personal life stress, and want my son's custody and divorce at any cost. Please note my no is [deleted] and my what's app no is [deleted]
