It's no secret that many JW marriges are loveless. They stay for fear of DFing.
Now gee, what could've caused that? The archaic courtship period...followed by engagement because the woman doesn't want to look like a tease, and because the man figures she's the best he can find...followed by marriage to get ahold of that sweet love-making...only neither of them know how to please one another...and oops! Other than getting married for the sack, there's not really that much in common....and oh boy, here comes a baby...so you better stick around for that, brother! And they wonder why there's a problem...
