Meaning

Hi friends,
I need some help to undrastand the following text, meaning of "bugs his clothing" and "confront" and "wlid card":

“Though Max isn’t her husband’s real name. His name is Phil, and she’s had this kind of problem with him before. She always knows about it—naturally she bugs his clothing—and he knows she knows. He’ll stray off-track—it’s an addiction with him, like gambling, doesn’t Stan agree, you have to feel sorry—and she’ll let him run with it for a while. It’s an outlet for him: in a gated city with one-way gates, outlets are limited for a man like him. When she thinks it’s gone far enough, she confronts him. That shuts it down.
But there’s never been a wild card before,” she says. “Oh, there have been wild cards, of course, over at Positron. We know what to do with them in there. But there hasn’t been one among“our own Alternates. Mine and Phil's."

Thanks alot
