Reports on Thursday suggested Redknapp was seriously considering departing Fratton Park after Saturday's Wembley showdown with Cardiff.
But the 61-year-old says he is staying at Portsmouth, and his snub of Newcastle in January was because he didn't want to be away from his wife. So why would she not move with him?
Redknapp: "Newcastle was a terrific job and maybe this sounds like a lack of ambition, but I didn't want to be away from my wife.
"It didn't appeal to me to be stuck up in a flat and coming back down at weekends.
"If I didn't like her I probably would have gone. Listen, I have turned down a bigger job than Newcastle this season.
"Only a few weeks ago, I said no because of similar reasons and, also, I don't want to walk away from here again.
"You're as old as you feel and Alex Ferguson (aged 66) must be feeling bloody brilliant. He's a lesson to us all.
"I want to go on as long as him and I don't see why I can't. I still love the game as much as ever. I've got a good team, good players and thoroughly enjoy working at this club.
"I can't see myself ever leaving Portsmouth, not now. It would be nice to put on a performance in the final but it's more important to win.
"In 10 years' time they'll only remember who won it, not how they played."
