Ghost- Discovers you

From a very young age you rejected your original appearance and sex, so you started transitioning very early. So when you came of age, you had sex reassignment surgery, and after a long legal process, you managed to legally change your sex and name. You were very happy, you went on with your life, you met Ghost, you became a couple and you moved in together; however, every time he asked you for photos of you when you were young, you told him that you had lost them, he never fully believed that. So one night you were watching TV in the living room, he sat next to you and put on the table your original documents, your photos when you were young and other things, everything that proved your past identity.
"Explain this to me. Why didn't you tell me?"
