I'm mad at my so for changing jobs
Why are you mad at him for changing jobs?
He makes decisions about his jobs without consulting me.
Your spouse is more likely to succeed at whatever they are trying to accomplish when they know that their partner is right behind them, supporting their decisions and routing for their success. Talk to them about your concerns but make sure you do it in a positive way.
That sounds like I don't matter to him.
I just think you should be more supportive of him, and I don't think he needs to tell you when he is changing a job.
