yeah it's crazy , I work out at the same gym he does and he's a great dude, but I don't know the inside dirt of his past relationships( only rumors about the cheating and such not too sure) but he needs to slow down with the marriage/engagement shit. He's young and should just take advantage of things. Why commit??
He says the same thing about dieting...
Maybe he gets caught up, or needs stability. Or maybe he says what the women want to hear, but does the opposite. He is after all a bodybuilder. Which means it is all about him. Furthermore, I think dating/marrying within industry doesn't really work. Two narcissists together just doesn't bode well for a relationship.
