Janet Gretzky runs shit in the Gretzky's house. Her kiss denial of Wayne is all the proof you need.
I think every guy's been there. It's one of two things, she's pissed at him or the love is gone and has been for awhile.
I'm guessing the love is gone. She didn't have that pissed off look on her face. It was more of the I don't love you, but 100% of your money is better than 50% and I'm not faking it for the camera look.
Bottom line is she's banging the pool boy and he's banging the maid.
