Hey Jeff, first off congrats on getting any response so quickly from your letter to W. Very well done!!
You see the changes in your W already - right?? She actually noticed AND acknowledged some nice things you did for HER. What a 180 for W! Don't push her too hard, let HER changes settle in to be a new behavior pattern.
You have it all worked out about dinner who is shopping, who is cooking what, when it is. What about cleanup? are those details worked out? will the boys chip in and help? everyone should do their part!
What is your W's parents like? what is their R for a role model? Your W has some deep issues for sure. Do you know if she was molested as a young girl? would she have ever admitted that? Also, she also lives in a house with 5 males, and just that could result in some resentment against males but I don't think to the level she holds it.
Go get a mattress! you've been talking about that for a year or more! Don't do it for W although it would take away one excuse for her to move back to the bedroom, do it because you are important! Go to a store that offers free financing and deferred payments for 6 months or a year and then your cc will be paid off before you pay for a mattress. BTW, what kind of mattress do you have in mind?? True I haven't shopped for a mattress for years but you make it sound like you're spending as much as a new car!
W wants to sell the house. Then what?
Live your life while you are still living. Riding the trail less traveled.
