As the couple's first child, Molly-Mae Hague, according to Tommy Fury, deserves more praise for putting up with his absence for training.
On Sunday in Saudi Arabia, the boxer will square off against YouTuber Jake Paul in a match worth millions of pounds.
Bambi was born to Molly-Mae and Tommy's family last month, but Tommy claims he has been busy training for the fight.
He tells Newsbeat that Molly "has taken it upon herself to deal with everything herself.".
She has never contacted me about anything.
She has been outstanding. People ought to stand up and applaud her greatly for that, in my opinion. ".
This is the third time the fight between the two has been scheduled; the first two dates were canceled due to Tommy's visa problems and his injury.
Even though they had just welcomed their first child, he claims that taking on Jake Paul is so important that he was unable to leave his training camp.
Tommy claims, "You can't break training camp; it's such a serious fight.".
"And the kind of sacrifices I made leading up to this are like this. What can you do? It is what it is.
Jake Paul posted the news about the fight before Tommy and Molly did, saying there were "no excuses, the baby has been born.".
When we saw it, Tommy says, "There were like 20 million people speculating about it, so we weren't that bothered.".
He didn't know anything and was located in the United States, so Molly and I thought it was a wise decision. ".
The fight is happening in Saudi Arabia, where it is against the law to be gay and there are strict restrictions on what women can do.
The nation has hosted several significant boxing matches in recent years, and it has been charged with sportwashing, or using these contests to boost its reputation abroad.
Tommy says, "I can only come and talk about my experience.
And so far, they haven't been able to do enough for us, which is amazing. Everything we needed was available at the drop of a hat.
Because there is so much to choose from and everyone is striving to be the best, I think this will be the epicenter of sport in the future. ".
