“You gave me the best years of my life. I hope I gave you the best moments and the best of myself and my daughters.

“Obviously I would like you with me. But I cannot be selfish, you could not keep suffering and fighting for so long to live."

“You told me in January you were going to die this year and I was annoyed with you.

“I will miss your calls, your presence, your scent, your touch, your voice saying sweet words to me - telling my ‘my little dumpling, you are beautiful ... the dish you cooked me was great,.

“The flowers you sent me to the office with your card where I can see you told me that I was the love of your life. You were loving me all the time.”

Son Pablo has revealed that his mother, del Castillo's grieving widow, is 'devastated'.
