I Accidentally Saw My Pregnant Daughter with My 48-Year-Old Best Friend at a Restaurant

I always believed the quiet would become easier once Mia left. No more arguments at night or doors being slammed, yet the silence was overwhelming. The final argument echoed in my thoughts—Mia, in the living room, saying she didn’t require my approval to date.
