Am I Wrong to Give up a Guy I love for someone who has a Secure Future?

I am not a materialistic person, I don't expect much in terms of money. I am perfectly content with a middlecl lifestyle. But the person I have been in a relationship for sometime now does not have a secure job and I am concerned about our future together. I am working and have a career, but I dont want to be the main breadwinner. He is capable of getting a job, it is going to take some time until he gets a career. Should I stay in a relationship with no security, but love or risk ending the relationship and finding a man who has a secure future?
