The workings of the male mind are sometimes bass-ackwards....He wants you to be the woman he married in 1999....but what is wrong with the woman you are now? OK, so you've gained some weight and wish to improve your body, health and self-image....
But you have nurtured a 6+ year successful, marriage and show INCREDIBLE patience. I would have been a lesser being and pointed out DH imperfections to him and pasted some photos to "motivate" him....
of course if your husband is a gorgeous hunk with a perfect body, this is a moot point......
