Chris Martin is taking responsibility for his “conscious uncoupling” with Gwyneth Paltrow. The Coldplay frontman has spoken up for the first time about his separation from the Oscar Award-winning actress.

Since Paltrow’s announcement of their separation in March, rumours about the couple’s alleged infidelity have surfaced.

Paltrow was first spotted giving an ex-boyfriend a kiss, though it appeared to be just a friendly peck to some. Martin was also reported to have cheated on his wife with British model Alexa Chung first, then with a “Saturday Night Live” assistant.

The cheating rumours didn’t last, and both Paltrow and Martin seemed to remain silent on the reason of their split.

But in a candid interview with BBC Radio 1, it seems that Martin has admitted to being the one at fault.

“About two years ago I was a mess – really because I can’t enjoy the thing that we are good at and I can’t enjoy the great things around me because I’m burdened by this,” he said.

“I’ve got to not blame anyone else and make some changes. I wouldn’t use the word breakdown; this was more a realisation about trying to grow up basically. If you can’t open yourself up, you can’t appreciate the wonder inside. So you can be with someone very wonderful, but because of your own issues you cannot let that be celebrated in the right way.”

He continued, “What changed for me was – I don’t want to go through life being scared of it, being scared of love, being scared of rejection, being scared of failure.

“...Up to a certain point in my life I wasn’t completely vulnerable and it caused some problems. ...If you don’t let love really in then you can’t really give it back.”

Although it was a cryptic statement, his message appears to be clear: his own issues stood in the way of his marriage with Paltrow.

The couple married in 2003 after dating for a year. They have two children together, daughter Apple (born in 2004) and son Moses (born 2006).
