"I've lived my life looking for my safe haven and the universe blessed me with your mother. I thought that life couldn't get any better and then the universe gave us you.
"I barely have a clue on what it takes to be a dad but I promise to always be there for you, to always make you feel loved and understood, to raise you in an environment filled with love and laughter, to be your best friend, and to be the first man who will love you unconditionally until the very end.
"I promise to never ever leave your side. Your mother and I will make some mistakes along the way but we will always find ways to make up for our short comings.
"ps. I hope you love music and bmws as much as your dad!"
At the end of his post, Xavi exclaimed, "IMMA BE THE GREATEST TO EVER DO THIS!!!! To my sun and stars, I love you so much!!!!!"
