Charlie has remained in contact with Matt since Busted split but no longer speaks to the last of the trio James Bourne, who has gone on to form pop band Son Of Dork.
He said: "We all live such different lives now - our paths don't really cross. I move in completely different circles to Matt and James."
He admits to being miserable for much of the five years he spent in Busted.
Although the band enjoyed huge success, toured the world and topped the charts, he always hated their poppy sound and wanted to play in "a proper rock band".
But he insists he has no regrets. He said: "The things I did in the past got me here and I love this. I can't look back on the past and think about changing things - that life led me to Fightstar."
Charlie was prepared for a difficult time winning over rock fans when he launched Fightstar - whose next single Hazy Eyes is out on June 5.
He said: "It has been pretty much what I imagined it would be - a real struggle. But as long as we stick to our guns, perform from the heart and let the music do our talking, we can't go wrong."
Fightstar's debut album Grand Unification is still selling well with another tour looming in autumn - after they play Edinburgh's Corn Exchange on May 31.
You might expect the band - Charlie, guitarist Alex Westaway, bassist Dan Haigh and drummer Omar Abidi - to be relaxing and enjoying the fruits of their labours.
But they're actually preparing to start work on the follow-up - and Charlie's excited by the prospect.
He said: "We've started writing again and are hugely excited about the next record.
"After the first one was released I was worried because I'd put my whole life into it and didn't know how I could do that again but now it is here it's very exciting.
"The first album was about putting down a marker, for me it was expressing to the world who I really am.
"All the built-up emotions from the previous years blasted out at once.
"Now people know what we are about so we can try different things."
