Then, with an eerie calm, Kate said, “This is Rebecca, your dad’s mistress.” The kids didn’t even react. I was stunned.
Kate didn’t waste time. She looked me in the eyes and said, “Let me get straight to the point.”
She told me she had known about Jack’s affairs for years, and while she had come to terms with them, having another child in the picture changed things. That’s why she wanted to meet.
Then something even more unexpected happened.
Her daughter, Lily, said they wanted to meet their baby brother or sister. I didn’t know what to say. That’s when Kate dropped another bomb: she had divorced Jack five months ago—something he never told me.
She explained that since I was having his child, she wanted her kids to know their sibling, and for my child to grow up knowing them too. I was speechless. It felt surreal and honestly, a little strange.
I couldn’t imagine being that kind if I were in her shoes. I doubted teenagers would want anything to do with their father’s affair child. But then Lily said something that touched me deeply—she said she already loved her baby sibling and couldn’t wait to spoil them and be a great big sister. Randall agreed, smiling at the idea of having a younger sister. I saw sincerity in their faces.
I left that café overwhelmed and full of mixed emotions. I haven’t told Jack about any of this. I didn’t know he was already divorced, and now his ex-wife and children want to welcome my baby with open arms.

I’m confused, emotional, and torn. What should I do next?
