Well...

I'd say get out if you want.

Home is where your heart is, and if your heart is somewhere else, you are better off somewhere else. If your heart is here, then you know your not kidding anyone, you are going to stay, otherwise you will end up constantly thinking about home, ending up with Michigan constantly in the back of your mind, nagging you with nostalgia and memories, so much that you might just end up searching out Detroit message boards to post all your old memories, along with comments about how happy you are in your new home in some other sweltering sunbelt city, like a smug dumpee who has to convince themselves they've made the right decision, or a boastful musician who has to constantly proclaim how great they are, but secretly know that they have given up a piece of themselves and sold out, and given up a love of their lives, for which can never really be replaced.

Follow your heart.
