Kaley Cuoco was gushing about her marriage to Ryan Sweeting when appearing on Watch What Happens Live on September 20.

But behind the scenes the 29-year-old actress was already planning to split from the 28-year-old tennis pro, UsWeekly claimed on Wednesday, because he was addicted to painkillers prescribed after a 2014 back surgery, it was alleged.

'She supported him but she said he couldn't make the commitment to get sober,' a friend told the weekly. 'He'd tell her he was working on it and instead go get wasted.'

It was added that she is 'devastated' their marriage has crumbled and has 'sworn off dating'. 

The weekly explained Ryan was sober when they married in December 2013 after only six months of dating.

The athlete - who once ranked number 64 in the world - had a history of trouble with pills.

A struggle: 'She supported him but she said he couldn't make the commitment to get sober,' a friend of the Big Bang Theory star told the weekly. 'He's tell her he was working on it and instead go get wasted'; here they are together in Janaury

In 2006 Sweeting was arrested for a DUI and possession of a drug with an intent to sell.

After they wed he 'developed a dependency on painkillers'.

When he suffered a back injury just months after meeting her, he was prescribed pain pills.

Earlier this year, UsWeekly stated Ryan had another injury that caused even more problems.

'Kaley told friends doctors prescribed something that he was taking too much of,' a source said. 'That is when it went downhill again.'

Meanwhile, Kaley was writing on her social media accounts that they were just fine, even though reports surfaced that the two were having issues.

But the troubles persisted. 

He promised to go to rehab in Boston, it was reported. But by the time he agreed to go, it was too late, it was alleged.

'She couldn't fix him. He wasn't the man she thought he was,' a friend told UsWeekly.

It was also noted, 'She couldn't take his ups and downs.'

And there were the fights. 'He'd lash out at her,' it was claimed. 

The two announced their split on Friday.

Cuoco had a pre-nuptial agreement drawn up before she married the 28-year-old tennis player.

In divorce documents filed by the Big Bang Theory star on Friday she cites 'irreconcilable differences' as the reason for the split. 

And now she 'isn't wasting any time ending their marriage,' a source told UsWeekly.

'She's ready to move on.'

A source added, 'They have been unhappy in their marriage for months' and 'this has been a long time coming'.

And the insider added that the TV icon has not given up on love. 'Kaley is still a hopeless romantic. She will find love again.'
