Terrible Wife

I feel like I have been a terrible wife. My wife and I have been together for two years and married for almost 6 month. At some point in our relationship something changed. Something changed in me. I am snappy and I feel like thing have to be done the right way (my way). Recently, My wife was offered an amazing job opportunity. This job opportunity is working with an organization that I have volunteered for many years. The job was offered to my wife, who only affiliation with the organization was ME! She has no experience and does not have what is a requirement of the job. She is now basically my boss! She really needed this job and pay raise. I never thought it would bother me but is does and I feel like I have turned into a huge asshole. I feel like I need to be more supportive. However, I am not sure how to be. Any advise?
