Hairdog, have you abandoned the plan of making The Statement every day? You did it for a couple of days and got some not-bad results. Then, it seems to me, you started to talk yourself out of it and developed a case of Paralysis by Analysis. The Just Do It approach is the one to use-- we can always finds lots of reasons for NOT doing something that is going to challenge our comfort.
How badly do you want changes in your marriage? If you choose to stay comfortable and hidden, just KNOW that you have made a choice and that you are not a victim.
P.S. Not saying this strategy will produce the changes you want, but it will push at least one person out of the comfort zone: YOU.
