I finally made some progress! I took TON of stuff to goodwill yesterday - a comforter, body pillow + 2 covers, big box of books, baby clothes, my clothes, some miscellaneous crap.
Husband, unfortunately, took a few things out of a box. I had a couple of Dave Ramsey books in there, as well as the Financial Peace DVD's. We both read the book ages ago (like, early 2012), and started watching the DVD's but didn't finish them. Now he wants to re-read the book (unlikely), and watch the DVD's (even more unlikely, since we didn't get through them the first time). These things have literally been sitting untouched for nearly 4 years. And the library has the book if he REALLY wanted it. I pointed this out but he doesn't listen to me. He also is insisting on keeping 2 huge computer towers that have been sitting in a closet for as long as the Dave Ramsey stuff has. He says he's going to build a computer one of these days. He also denies telling me that I could go ahead and toss them. They're ancient; even if he did build something (again, very unlikely), he'd probably end up wanting to upgrade. I told him fine, keep them for now, but I'm not moving them again. We've moved them twice now and they haven't been used. We are probably buying a house next year, and none of that crap is coming with us unless it's actually being used. He agreed. We'll see.
Lesson learned: don't let husband see what you've packed for goodwill.
