I agree with 3.1416 totally.
Your resume will thank you as well either way. Employers can understand a full time push to finish an education or your decision to move to a new job, a lot better than they can understand reduction in responsibility and job breadth. Unless the jerk goes away, you are dead end and unhappy.
Finishing school, whether full or part time, will do more for your long term earning potential, than diving full time now. It doesn't take a colledge education to simply be a good coder, but it is rare for someone who is only a good coder to be successful at the rest of the development business.
Good luck!
