Relationship vs. parents

Isabelle

Ive been exclusively dating this one guy for about two and a half months. It’s midnight and he just about left my house. After that I over hear my mom saying to my dad “do you think it’ll last?” And him replying “no” about my relationship. They know that this isn’t just some random guy I like. He really means something to me. Should I confront my parents or just let it pass? How should I go about the situation? What would you do if you were in my shoes?

EDIT: Some people were wondering how old I am, since this does involve my parents. I’m 21 but I do still live with them. Thank you for the advice everyone. Most people are telling me to just let it go so I think that’s what I’m gonna do
