Never ending post-marital aggravation

Although I decided to quit harping about the concept of modern marriage - mainly, how unrealistic it was - it now seems that it can continue to bite you even after one dissolves the relationship.
Over the past few weeks I've been cheerfully waiting for my tax refund. It was more than I had expected, because last year I'd jiggled my paycheck deductions to lessen the refund. It didn't make sense to let the guvment make money off my own money; I would be better off parking it in savings during the course of the year.
I admit I already had plans for the extra money. A friend of Ryan's was selling his Triumph Speed Triple, as his wife was verbally abusing him for adding a pricey Ducati to his motorcycle collection without selling one of the other bikes. So I had decided to use my tax refund to get a slightly bigger motorcycle.
But yesterday, fate vomited upon my eiderdown once again. It seems that Estranged Husband owed back taxes as he hadn't bothered to make his quarterly tax payments in 2007. And since we had filed a joint return back then, the IRS didn't care which of us actually paid the taxes, along with the penalties accruing during the past three years.
I don't know the exact figure, but chances are my refund will be zero.
Estranged Husband apologized, and said he would pay me back. But not at one time.
I suppose I'll just have to look at the lost refund as yet more of the costs involved with breaking up with one's spouse.
The only bright side to all this is that Ryan's friend's wife had quit nagging him to sell the Triumph (at least for the time being). So he's actually happy I had to renege on the purchase.
