People will usually leave their spouse if the woman is unable to give birth, but your husband is like an angel he is still always patient and faithful to accompany your days with you, it proves that he really loves you sincerely.
Your choice with your husband to adopt a malnourished baby is a very noble act, you raised him with love until now he is very healthy and has adequate nutrition.
Your struggle to have a baby is very inspiring to me, I am currently struggling with my wife to have a baby. I ask for your prayers.
Hola amigo a veces Dios nos manda a los hijos desde otro vientre y eso fue lo que nos sucedió y lo amamos como si hubiese nacido de nosotros, y él nos ama también, no pierdas la fé, saludos.
What you said is amazing, I agree with your opinion that "she was born for us," may you and your husband always have God's help.
