What do you think is telling you to stay? If you do decide to stay you can always leave later. I think too many leave anywhere without be ready to. When your ready you will know it. :)

I say you move away somewhere, give it a years and think about it then. I think thirty's the sort of age you should really start to think about where you want to be. Go see the world for a while.

Make your list of pro and con for each place

Then dont go by the number...look at how important each item on the list is to you

maybe you can spend half the time in one place and the other half in the other place

Follow your gut....
