Skiekitty, Keep growing roses and dreaming! Really. Because good dreams can take you in good directions. And maybe you'll have a chance to grow roses someplace more to your liking. Alternatively, maybe your roses will help you feel a sense of your own place where you are. As I know you are finding out, a self-built rose garden can provide a powerful and gratifying connection to a place.
I also realize that some of us derive much more pleasure from acquiring new roses and designing them into the garden than we do just watching the garden grow and tending it. So more space seems better. I've been there. All I can advise is to get a camera and take photos. And maybe take up another hobby that takes you into the neighboring countryside - something like hiking or biking. These, too, help us connect with where we are.
And finally, as you dream about living somewhere else, try and carefully assess what it is that you want. Not just out of your roses, but out of your life. Don't take for granted things in your life that you now have. For example, when we bought this house we imposed the banana principle. Houses 40 miles out from Prescott cost about 2/3 what houses near town cost per square foot. But you had to drive 20 minutes each way to the grocery store. Out of bananas? There goes 40 minutes of your life. That's not what we wanted. Ironically, we don't go out very often. But when we do, we find it's really nice to have a grocery store, an Indian restaurant, and a Kinkos just 5 minutes away. It's just an example.
