Both my parents are having extra marital affair
Yes, you read that right.
I was 17/18 when I found out my mom was having an affair with an uncle who's close to my family. The uncle is married too who literally has a grandchild now. He's from my mom's hometown and he's a temple priest. I was having my government exam when I found their chat on her phone and it's literally the worst time to go through something like this. I was using it for my studies, then a chat came. Which obviously as a curious kid at the age, I opened and found things a child should never see. I was crying for days and weeks. Contemplating if I should confront or shut up about it. Not being able to act fine in front of her anymore. Feeling bad for my father. Thinking if I should at least let him know cause he deserves the truth. At the end, I didn't do anything. \[If yall wanna know in more detail, can scroll down my past posts. I might have said more there since it's been years I found out about mom's.\]
Then, years passed. I'm 21 now. My mom's affair is still going on. Few months ago came my dad's birthday. Dad's phone was on charge and a text notification came. There I saw. A woman wishing my dad "Happy birthday, we met at club 9 years ago and it's not been easy, but the best for sure". My reaction? I froze. I've seen this woman's name on his phone earlier this year and he was calling her 'Darling'. I thought I misread but no, there it was clear as daylight. I snapped a picture of the notification for whatever evidence.
I'm the first child and I have a younger sister. At the beginning no one knew about this affair except for me, I was sure. But now I think my sister might just know it. Maybe not as much as I do. Some may say it's their life and up to them, why should I bother. Yes of course, until you're the child witnessing not one but both your parents having an affair. I hear them talking to these people everyday. Walking away privately when they receive call from the person (i know since they have a specified ringtone for each). I'm so numb.
I have a boyfriend and he's the first person I shared everything to. Today my mom was supporting her favourite actor's affairs. There's pics and videos but she was calling them AI when she can't even differentiate an obvious AI dog video on Facebook. So I fought to her about it. Then when I was telling him what happened today with full anger like how can a person support such act just cause they're your favourite actor, his reply was "Don't be too mad over such things, let it be. You get mad too often over such small matters" repeatedly. I was reading the text with tears in my eyes. Yes, I'm known as the angry child since I was like 5. Plus I'm a girl, so it's always "as a girl it's not good to get this angry". So to hear this same thing from my boyfriend who knows exactly what I grew up witnessing and why I am how I am was simply so heartbreaking. I told him this will be the last I ever talk to him about it while he just kept apologising.
I just don't know. It's them who's having an affair but it's me who's so mentally affected and exhausted. Even if I try to share it finally, I'm told I'm being too much. What am I even supposed to do or how do I even take care of myself mentally?
TL;DR : Both my parents are in an extra marital affair and I'm mentally affected seeing it happening in my home everyday.
