QS, didnt you say your wife was keeping some things of hers in the freezer?
She can't force YOU to pay for all the utilities and continue to use the equipment dude...
Toss her crap out if she isnt' going to ante up...
I know she's angry, but if you stand up for yourself she will have more respect for you...
You COULD make the argument, and tell her you COULD and thoguht about it, but decided you will be gracious enough to allow her things to stay... your call... but assert yourself one way or the other...
