'Big Bang Theory' Season 9: Kaley Cuoco's Worries About Cheating Husband? Ryan Doesn't Want Kids

Could Kaley Cuoco and husband Ryan Sweeting be experiencing marital trouble? 

According to reports, "The Big Bang Theory" actress is concerned about her husband's commitment and ability to remain faithful. OK! Magazine shared in an article that the 29-year-old celebrity is starting to doubt how well she knows her husband and his nature. Given their whirlwind romance, a source says, "[She] is secretly worried she doesn't know him that well." 

In a related piece by In Touch Magazine (via Celeb Dirty Laundry), there have been times when Ryan has disappeared for lengths of time and she had no idea what was happening during those times. 

"Ryan was apart from Kaley for weeks of training in March, and she would flip out if he didn't answer his phone. Since he has been back she doesn't let him out of her sight - it's driving him crazy."

Earlier this year rumors of a rocky marriage began circulating and speculation began that the fairy-tale romance of Kaley may be crumbling. In a previous report, OK! Magazine detailed that their problems started when Sweeting's tennis career started to dip. 

"Ryan sits around their home all day, and they have huge fights where she tells him to figure out a way to make his own money," leaked an insider to the publication. "The truth is, they got married before they really knew each other, and now it's evident that they don't have anything in common besides loving their dogs."

This went hand in hand with a Life & Style report back in March that says another issue the couple is working out is whether they want to have kids. 

Apparently, Kaley has been eager to start a family but Ryan isn't quite in the same place. The constant fighting stems from the fact that the pro athlete isn't ready to be a dad yet. 

The insider continued, "He's been pushing it off for a while now. And he recently told Kaley that he's not sure he wants to have kids any time soon!" It was even published that Kaley is so adamant to start a family, if this isn't something that Ryan is willing to budge on, Kaley is said to be "ready to walk."

"She wants kids soon, so this could be a deal breaker for Kaley," reported Life & Style. "If Ryan doesn't change his mind, they'll probably get divorced."

The pair were wed after a few months of knowing each other and tied the knot New Year's Eve of 2013.
