First, the dream is not so much about her as it is about how you feel. Taht your old work, and her, feature in the dream is simply because your subconsciosu finds the memory of both easiest to relate to your problem. You said yourself that the descision you made has kept you form moving forward in life. I think the dream is presenting the whole image as a dance of sorts. It's a cold hearted sort of tango, where you are dancing effectively with yourself, but never really approaching the problem....the root of your stagnancy...head on. Instead you dance around the issue, bantering lightly at it and skirting the possibility of discovering what about the whole even truly led to your emotional conundrum.

Your dream is challenging you to face the depression head on. It's a calling to get past the superficial part of it and dig into what is really keeping you in your rut. Most of all, the dream is a mirror held up to your own self, as you shuffle around trying to avoid the issue. "See," it says, "You can't get any progress when you're dancing like that."
