We were all even more shocked when they called it quits…until we took a closer look at their relationship. Here are a few reasons why the Cougar Town star and her Irish-bred rocker would never last. That's too soon for most normal couples to decide to a lifetime commitment, let alone two stars faced with the pressures of Hollywood and careers that will keep them separate for long periods of time. The pair got serious in the honeymoon phase—without having to overcome any obstacles yet.
But that doesn't mean it's not an issue. Cox is 51 to McDaid's 39, and they may have been in different places in their lives: Cox is a working actress who's financially set for life and already has a marriage under her belt, while McDaid is a rock star still in his prime.
Those guys aren't usually quick to settle down, and reality may have hit him hard once the rose-colored glasses came off. Seriously, how '90s is that? They constantly fight about it. Pardon us while we take out the world's smallest violin. Their Personalities Clashed Sources close to the couple told The Sun that the pair's opposite natures may have attracted…but they never would have lasted.
She is tough and doesn't suffer fools. Johnny is laid back and their personalities just clashed. She would try to mother him and he didn't like it. It clearly didn't work: A source told Page Six, "He's actually the one who instigated the breakup. Johnny feels she's a little too close for comfort with her male co-stars. He doesn't like the fact that she's close to them, that she stays in touch with them [because] she has this past of falling in love with people she works with.
He feels very uncomfortable. Of course a healthy co-parenting relationship is great, but the former couple are pretty much best friends.
That's enough to make even the most secure guy a little uneasy. The ladies are together frequently, and apparently all that girl time didn't sit well with McDaid. Radar Online reports that Cox was the last to leave Aniston's wedding to Justin Theroux in August, and McDaid told her that "something…didn't feel right. He had enough of the scene and just wants to focus on his music. She wants to be with him," the source said.
When he completely cuts off after a split. An insider quipped to Page Six, "He upped and moved. She doesn't know where he lives. It's really bizarre how he's handled things. He's very cold, completely closed off from her.
