I am sorry - but this just seems a bit sexist - of course girls don't hate maya. Why would they? As happymat27 has already pointed out, there are a few women members on this site and a number of well respected women in the industry. Sure, it might be male dominated at the moment, but that is bound to change.

It was my girlfriend who got me into maya - and I imagine that there are a lot more women who are into maya and Computer animation and video games than you might think.

It just sounds like you are not spending enough time with your wife. I am sure if you spent some time devoted to her, she might not be so grumpy.
