I feel like stopping my husband from having his dream job at 25 years old
Why would you not let him have his dream job? This is a good thing.
My children are more important to me than his dream.
You married him so you should be more supportive especially if it's his dream job. You shouldn't prevent your husband from success. Think of it this way, his success will actually be your success.
Well it's an entry level job and I am the bread winner of our home and the family.
Just because you make more money doesn't mean he shouldn't have a chance at having a job he loves. His job may lead to success in the future and allow you more freedom too.
