In the ongoing arms race that is marriage, I'm afraid she's gone nuclear while your still figuring out the bow & arrow. In a nutshell your toast.
Think your going to replace that cracked tank anytime soon... good luck! Start saving your money 'cause you know the half dozen things that she's been hinting at wanting... she's getting those before you get yours.
Hopefully you can repair the tank. I took me a year of good behavior before I replaced my 125 when it sprung a leak. In the mean time, she had the exterior of the house painted, I had to tile the kitchen floor, and I built her some floor to ceiling bookcases for the office for her to organize it with (been 2 years and she hasn't yet).
Now I'm thinking about a cichlid tank in the corner of the family room. We've talk about putting one there for years. I think that I may have to do some major work on remodeling the kitchen this winter to get it however.
