I always tell DH how much I SAVED him, not how much it cost him. I don't work outside the home and as a SAHM certainly dont bring in a paycheck that you can see in our bank account. DH has always been supportive of al my hobbies and encourages me to purchase what I need when I need it. It breaks my heart to hear stories of those women who much "ask for permission" to spend money they have learned.
You need to do what is best for you and your financial situation~who are we to judge?
