OMG I need a valium or a large rubber mallet

I'm sooo pissed off right now I could just scream.Aaaaaaaaaaaaaaaaahhhhhhhhhh. I have a pretty good relationship with Potsie my ex and I work hard at keeping things friendly and calm - better for the kids to have parents who can smile and laugh together. We only have one leetle problem - money. Not all money just a line of credit that we had on our house - when we went our seperate ways he got the house and agreed that the LOC was his as well. Seems he forgot to inform the BANK of this and today when I went grocery shopping, there were was a hold on my account. They took MY money to make HIS payment and of course he's on his way to Florida. When I called his house, his g/f starts giving this heart wrenching story about how broke they are yadda yadda yadda. He makes at least four times more than I do a year plus her earnings and the bank is taking my grocery money??? I'm absolutely furious with him for putting me in this position. I can't WAIT until he calls me from Florida. I wish I could say I hope it wrecks his week but that would be vindictive wouldn't it? When I calm down, I'm sure I'll be a better person but right now I think I'll go and stew for a while and stick pins in my Potsie doll.
