Looking for guidance.
I'm 17 (M) and my mom is 35 (F). To give you a bit of background, the relationship between my mom and dad (43) is quite complicated. They separated in the past but never finalized a divorce because my dad loves her deeply and would do anything for her. However, for the past three years, I've discovered that she's been chatting with other men, including flirting and sending pictures. My dad is aware of this and had her block all of them after they had an argument. Now that my dad is working abroad, I've become increasingly suspicious of my mom's behavior. Tonight, after she left, I decided to check her WhatsApp. I found the blocked contacts, but then I stumbled upon a chat with a schoolmate. In it, she mentioned that she made a boyfriend at the gym and described him in a very explicit way. When her friend asked if it was a one-night stand, I realized what was going on. My heart raced, and I felt a wave of pain hit me. I tried to message my girlfriend for comfort, but she was already asleep. I feel torn about whether or not to tell my dad, especially since he lives so far away, and I'm worried he might react poorly. Part of me wants my parents to divorce because my mom has made my life difficult since I was six. I’m really unsure about what to do next. I'd appreciate any advice you can give.
