Simon Thomas revealed how touching his son Ethan copes with the loss of his mother.
The former Sky Sports presenter shared a handwritten letter from his eight-year-old son on the day he talked about the "early stage" of a new relationship, a year after his wife Gemma died.
"The way my boy copes with his mother's loss continues to inspire me and fill me with hope," Simon tweeted.
"He wrote this yesterday without prompting and without help."
The touching letter is: "Hello Daddy, I have good and bad news for you … Good Halloween is over … Bad we miss Mummy !!!
"Grief is hard to handle, but together we can make it through this raging storm of grief! I love you."
Today, Simon said his new relationship was "an incredible support" for him after losing his wife to leukemia.
"I am very aware that she was somebody I did not know and met in the past weeks and months," he told Anna Foster on BBC Radio 5 Live.
"From the beginning – she had this compassion for me – she's also a Christian and that's important to me as a man of faith.
"She was an incredible support to me, she was the only person who always picked up the phone.
"What I saw in her, I saw in Gemma, when she said my phone was always on, she meant it."
When asked if he's in love again, Simon admitted, "I'm coming there, yes, it's strange in many ways to feel that way again."
But he insists he will never abandon his wife's death and Gemma can not be replaced.
"Sometimes I struggle with the phrase" go on "- I do not think you'll ever really do what happened," he said.
"This hole left by a beloved person does not shrink over time. Life begins to grow.
"You're starting to deal with some of the challenges that grief causes when you're a single parent.
"I have two options. Give up – I can not do that, I do not want that, I have a boy I can raise, I promised Gemma.
"The only other choice is that you go.
"From the beginning, I had the feeling that I had to find life again."
And he does not want to feel that his wife has been "replaced"
He said, "This may be an area that can cause a lot of pain. There are a lot of misunderstandings that result from this – we meet the meeting with another with the forgetting of the person who has gone.
"There are no shoes left to fill. There will never be another Gemma. We are unique – we come with our different personalities at the table. When you enter into a new relationship, the comparison is ultimately a futile task. There is no comparison. "
"It's not my fault what happened to Gemma – nobody's to blame.
"This person helps me to redefine life and helps me to be happy again.
"I can fully understand why some people do that [feel that way], But for most people we lose, they do not want us to remain in this empty landscape of grief. "
Simon also talked about the prospect of introducing his new relationship to the family of his deceased wife.
He said: "The difficult thing for Gemma's family – they have not met her yet. She does not want to look insensitive, since she starts there, here I am boys.
"When the time comes to meet, this will be a very physical presentation, a very painful memory of the physical absence of Gemma.
"We have to take our time.
"The things that go on around us can sometimes be pretty hard to navigate. The rules for the engagement are really very difficult.
"In truth, she chose a much stony path than she could have done."

In July Simon spoke of his continuing grief after the tragic loss of his wife Gemma.
Gemma died of leukemia just three days after diagnosis in November of last year, leaving behind Simon and her desperate eight-year-old son Ethan.
At the Lorraine Kelly Show on Thursday, Dad Simon said he still had to come to terms with Gemma's sudden death.
"I think part of the problem is that it was so brutal that it happened at the wrong time in life," he said.
"We all know that when we're hanging around, we'll eventually deal with a parent's death, or whatever it may be, and we know that sadness will affect us at some point.
"If it happens at a wrong time in life, it makes life difficult for people," Simon admitted.
The former Sky Sports presenter added, " "If you are next to me and [my son] Ethan, maybe you're in our house, and you see how big Absence Gemma is at the place we've been living together for the last eight years. She puts these people, my friends, before her own mortality.
"And the idea that maybe, even though the statistics are heavily weighed against the events, it might happen to them and it's a terrifying thought.
"Well, I think it's sometimes easier to step back because you do not have to factor in the reality of what might happen to you, but probably not."
Simon then said that his son Ethan struggles to open up for him after his mother's death, even though he is his only immediate family.
"His grief manifests a bit more," said the presenter.
"A child wants to protect you and does not necessarily want to tell you everything that goes on in your head, I sometimes know when he arrives next to his aunt Rebecca, Gemma's sister, he was very expressive of how he feels and what he's going through because I think he wants to protect me a bit from what happens because he knows that I'm worried and maybe I'm crying.
"I've always been very open in my emotions, the only thing I hold back from him is anger, because I do not think he needs to see that."
The father told how he still bursts into tears because he had done everyday tasks with Gemma.
"I was upstairs, mountain of lingerie […] I try to get through everything, I think: "I did not make the garden, I have to cook his tea." All the things we shared earlier, now just for you. And I just started crying. It hit me again, I'm alone, I have to go through this alone. Within 20 seconds, I hear the feet tripping up the stairs [Ethan] come up and hug me hugely. "
He added, "Loneliness is brutal … you have plenty of time for yourself with your thoughts.
"It hurts, it's a brutal leap to much emptiness, and when Ethan's eyes are closed, the house is quiet."
Simon said he is now writing a book about the loss of Gemma last year. When he's done, he plans to take Ethan on a road trip in a camper van to make happy memories together.
