I would just fess up after all what he is going to do? Probably pitch a fit and yell but then hell get over it. You will not be able to enjoy the item you purchased if youre always worried about the lie coming back and haunting you. My husband also gets on my case about the amount of money I spend on quilting but i just remind him that it makes me happy. I do however talk to him before making any purchases over $100.00 ecpecially if I have already purchased other things recently. Other than that he doesnt pay much attention. Maybe next time just talk to him about it then start bidding then you dont run into this problem.. Also, if it was truely your money that you got for your sole use then there should not be any problems. If it presents a problem then it probably was both of yours money which means that you probably should discuss large price item first. Hope this helps.
