A sacrifice from a daughter

I cannot believe that girl is used to be my husband, 11 years ago me and my husband always want a child but the doctor says that i can't so he have an idea that surprise me, one day when i got home there was a 9 years old girl wearing a hijab same like mine but smaller and she start to say "hi, Mommie!" with a cute face and a smile and i was crying like a baby, then she said "i know that we want a baby but we can't so i sacrifice my life for so, and i will live as a girly girl, under your supervision, wear lots of dress, become a good muslim girl, and never make you depress" and i hugged her.

Now, her boyfriend just propose her to be his wife and she said "yes a thousand times yes, honey!!" and then they hold hands and stares each other.
