I think my mom cheated on my dad when they were married?
So I'm 13 now, and my parents got divorced when I was 6. My mom then started seeing my stepdad soon after. Then they got married when I was 9. Today my 10 year old stepsister told me that her mom said that my stepdad slept with my mom while my stepsisters parents were still married. Then I realized that both of our parents got divorced around the same time, so I think that my mom might have cheated on my dad. What do I do? I get really mad every time I see my mom or stepdad now and I've been trying to avoid them all night. Should I ask my mom or my dad? And should I tell my mom about what my stepsister's mom said about her? The whole concept scares me and I've been crying all night. I need help soon, please.
