Is the job you have where you are something you LOVE? Of course, I'm assuming that they will pay you more than you are getting at your current job. And, is there no way your fiance could ever join you in LA? I once turned down a great job (in Antarctica ... it would have been wonderful) because of a guy who didn't want me to go (not as understanding as your fiance). The relationship ended and I never got the chance to go again. If working in the industry is important to you, then take the risk.

Could be worse, could be raining.
