I come from a Indian Muslim family, I live with my parents and a younger sibling on the outside we're the average family that you would see when in fact there is a family secret that only 4 of us know.My parents have been married for 22 years now. My mom is a revertee (she was brahmin) they meet when my they were in college and "fell" in love then somehow got married. My mother's family accepts her and we still visit them quiet frequently. But during the early years of my parents marriage and also a couple of years after I was born, my dad used to hit my mother (with belt etc) but after they had kids my dad stopped for a while but I vividly remember them fighting then and now but it became worse when in 2016 when my mom started to have an affair with a guy who was 20's years younger to her, my mom might have meet him through work. I started picking up hints whenever she acted weird and shut the door to talk to someone when dad wasn't home or she would start going out to meet her "friends" since she would usually take dad too because they had mutual friends and once when I borrowed her phone to Google something in her last searches I would find things like "good morning message for boyfriend" "I love you texts for boyfriend" I was shocked and disappointed at the same time and felt an internal conflict on whether to confront her on it or not . Anyway, it all got clear when I was in 8th grade and one weekend when I was getting ready to go to tuition when my mom was supposed to be at work, I saw her pulling up in an unknown car with some guy, and this was when I was heading out, she saw me and panicked (I could see it on her face) that's when she hurried me to go attend my tuition, I wouldn't be back until afternoon, after I left i slightly turned my head and caught a glimpse of the guy's face and recognised him from my mother's work place. That entire day I felt out of it. When I later came back home my mom was taking a shower and she had cooked Biryani and sweets and there were two plates in the sink instead of one, and I knew for sure my dad hadn't been home. By this time I knew she was having an affair and I harboured hate against her when she would lie straight to my face about it (her "boyfriend" gifted her a pendent with her initial once, she hid it in the kitchen but I found it on accident. The next day she started talking to my dad about how if she ordered for herself a pendent online and then after a week she pretended that it had arrived and showed it to us) she then continued her affair. And now I was starting to feel disgusted about it, but I was too scared to tell my dad because I thought he would murder my mom and I couldn't talk about it to anyone else either so I put my thoughts down in a letter and hid it under my mom, which my mom found later and read it, but pretended like she didn't and had never asked me about it or admitted to having an affair till date.
