I've done this so many times for different reasons, but what I'm hoping is different, though, is your reasoning. Did you move to help the family member? Is it something you want to do or are you feeling obligated?
Also, ask yourself the really big questions.
Is this a temporary move? Is it something you can adapt to and make the sacrifice to help this person? Will you feel good that you were able to help and be able to move back to the city later?
Are you afraid of change and leaving the familiar, feeling out of your comfort zone? Are there other ways you can find to feel more connected? Will you feel comfortable walking away in a year or two if you find you're not adapting?
Give yourself some food for thought. Make yourself a list of the pros of the move (ideas: gardening and fixing a home up can be therapeutic, you can see the stars in the night sky etc).
I do like the urban boyfriend, country home and having the urban boyfriend and the house, kinda like an interesting threesome.
