Whenever I meet someone who lives or has lived far from where they grew up, I usually ask what brought them there. Half the time the answer is a relationship, and for nearly all that half the relationship is long over.
They never seem to regret it — how you arrive is less important than why you stay — but moving in together is tricky enough. Combine it with a long-distance move, and you have two stressful life events. So whether it was you who went the distance, or your other (maybe former) half, tell us what you would and wouldn't do again.
