Gary Barlow felt like an "enormous weight" was lifted when he ended his 15-year feud with Robbie Williams.
The pair rose to fame together in boyband Take That but their relationship turned toxic after Williams quit the group in 1995 and they endured a public war of words for many years before they finally made up in 2010 with the Angels star rejoining the band for an album and tour.
Barlow has now admitted he hated feuding with his former friend and is relieved they've put all the bad blood behind them now, He told The Telegraph newspaper: "Thank God it’s all over, that stuff, because it went on for years. And I tell you what, it’s like carrying a weight around with you.
"It’s not nice to dislike anybody, really, especially someone you’ve been close to."
Barlow has been forced to relive the past for Take That's new self-titled Netflix documentary and the singer admitted reliving the past was tough.
He said: "Thank God we’re here laughing about it, and telling the story of something that’s in the past, because when we first met and made up [in 2010], it was such an enormous weight being lifted.
"It’s a traumatic feeling, it really is. And watching it back is very, very hard."
He added of the new documentary: “I’ll be honest with you, it took me about a week to get through that second episode.
"It was a really, really hard watch. A lot of the things in it, I haven’t thought about for a long, long time, and they’ve actually stuck with me since viewing it."
In the interview, Barlow even hinted Williams could rejoin the band once again or former member Jason Orange could make a comeback in the future.
He said: "With this group, we never know what’s coming next. The idea that someone might wander in through the door one day; bloody great.
"I mean, we’re very open to it. However, I think we’re a very happy band at the moment, we challenge each other, we’re making good music together, we’re excited about the next few years."
The three-part documentary Take That is released on Netflix from January 27.
