I know because I have "6 monthed" myself to the nth degree. Nothing changes if nothing changes, huh? My problem has been that my husband has always done just barely enough to keep me hanging in there...never to the point where things are good - just to where they aren't "as bad".
I too have 6 monthed myself to death. I 6 monthed myself for years. Mine too threw me enough crumbs to leave me hanging for years. (prior to the last two years - I should say). He worked, did little around the house, started things ~ didn't finish them. Along the way I lowered my standards. If it's 6 months and you MEAN 6 months, it's a great plan, though I'd say is still too long. I'd be leery of the 6 months ending around a holiday though.
