I agree with Isis when it comes to your boyfriend. Also, it may be just because he was ingrained with the concept of a job being the answer. Many people fear getting into self-employment because they don't see it as "safe" or they see it as "too risky." My guess it that he believes he's just looking out for your best interests and is trying to protect you. Be up front and let him know that you understand that, but you're following proven success models, and if he's still got issues ... then you can call him a jerk.
Just remember - success is revenge!
