[ 'Because it isn't important'; that's what Yuji wants to say, the kind of thing that's going to get him in a hideous amount of trouble if he actually admits it aloud.
His happiness isn't important, in the long run. Yuji has made his peace with that and recognises that all of this fighting would end with his demise; it is his role, in this world, to sacrifice himself for the hopes of the future. He had made that agreement as the Vessel of Sukuna, knowing that his success as a vessel would mean the loss of his life once they'd collected all the fingers. He had come to terms with that so long ago.
Now... Now he wonders how he can express any of this and have Fushiguro understand, have him recognise what Yuji sees as his role, his place. Saying all of that to Fushiguro is going to be something that just causes more problems, and that's why Yuji bites his tongue, forcing himself to swallow back all the awful things going on inside his head.
It's better not to consider it. ]
Think about yourself first. I'll worry about myself.
