Jealous of my boyfriend

My boyfriend is a wonderful guy who works hard. We both currently work at two different places but receive the same amount of pay.

Him and I have both been looking for new jobs using some websites online. An employer from a website contacted my boyfriend asking for an interview. If he gets this job, he'll be making 4x the amount I do.

I feel like a sh***y girlfriend because I want him to succeed and do well and make a lot of money, but I'm jealous that he got an interview right away and (most likely) will get the job.

What's wrong with me? Him getting a better income is better for the both of us. It just bothers me that I'm working just as hard as him to find a better job and he gets asked by a company for an interview. I feel so bad that I'm feeling this way. I want him to get the job but I want to succeed too.

Is it wrong that I'm feeling this way?
