What the fuck.

I need to rant before i do something stupid. So my mom has been with my step dad for 13 years !!! 13 damn years. He has 2 kids from his previous relationship. His ex wife and his kid live in another state. His ex wife is married too . Actually, has been married for like 11 years too. and has kids with her husband. My stepdad and her have always had communication due to their kids. Well yesterday . Sadly, my mom found out that her and my stepdad have been talking for some time . sexting and sending intimate pictures... im sooo heartbroken for her. It got me fucked up. and i dont know how to react. My mom doesnt like problems, but im not my mom so im thinking about sending her husband the screenshots of the conversation. because he doesnt deserve that either. and texting her telling her how disrespectful it was towards my mom ... 😭😭😭
