"It's ok that I spent all this money, because I saved money doing this other thing" is the mating call of every stupidly, intentionally poor person in the Western World. It's the middle-class equivalent of "I can go into debt to buy this because I'll be able to pay for it as soon as I get my tax refund."
Sorry, "honey:" that's still a lot of shopping, and you probably still should be saving more and spending less. And your mother forgetting to pick her husband up at the airport doesn't change that fact in the slightest. It's just a mean piece of misdirection that isn't going to improve your credit score.
