Yeah, who needs to show loyalty to a woman who carried his ass and supported him for years when he can get a young whore who will leave him at the drop of a hat. 
Although I get kreator's point [I myself enjoy a variety of hot, young, fishy slit], Kerry was Jay's high school sweetheart, and was very loyal to him.
So yeah, I get your point, HN.
That said...I think Kerry wanted Jay to retire. In an Ironman interview in 2002, Jay said he was to retire at 32 [2005], as he felt he would have a accomplished everything he wanted to at that point.
By age 33, he was Mr. Olympia...but he still didn't retire.
Kerry asked him "When will this end?", and I think got tired of it all.
Sad, but...I get it.
Is Jay's dad still alive? If so, he would be 92. Jay will be 46 in August...so his dad had him rather late...over 45. I know he was alive in 2012. Does anyone know if he's still alive?
