The "Joke" is that brides are smiling as they walk down the aisle because they know they'll never have to give another blowj--. Ha frikkin' ha.
Kid, the "leverage" the others mention is very real. Once you commit, they've got you by one ball. Then come the kids, and you realize that the other ball is caught. Oh, and along come the joint financial obligations (house,cars) and the comfort level of dual incomes, and then it takes, figuratively speaking, Herculean strength and fortitude to wrestle free. And by "wrestle free" I don't just mean the ultimate - divorce. I mean the boundary changes that are necessary to actually get the LD partner to commit to and make the necessary effort to change.
