Before becoming romantically involved with a coworker, you should carefully consider possible present and future consequences.
I believe that you should think it through if you want to pursue a relationship with a coworker, because, what if break up with them on a bad note, but you adore your job? Going to work may become a nightmare for you. Your coworkers have nothing to do with your personal life, and your boss cannot forbid you to date anyone outside of workplace. You shouldn't look for a new job just because you are attracted to your coworker either.
