Sounds like you and your girlfriend need to decide who wears the pants.

Don't get me wrong, I do everything I can to keep my wife happy but she understands that sometimes I have to make career decisions she is not entirely happy with in order to be able to support her. When she gets pi$$ed about my choices I let her know I would be more than happy to let her pursue a career and I'll stay home and look after the house. Unfortunately she still makes me work.
