A spouse who's not in favor of discovering what life might be like somewhere else can be a deal-breaker for the idea altogether. You can't very well pack your better half's suitcase for him (or her), take him by the hand, and lead him out the door (as we did with our then 8-year-old daughter when she made it clear, on the eve of our planned departure for Ireland years ago, that she was not on board with the whole moving-to-a-new-country thing).
You could launch a more comfortable, more interesting, safe, pleasant, even adventure-filled life in a number of places around the world on a budget of as little as $1,200 per month or less. In some parts of Panama, Colombia, Thailand, Nicaragua, Malaysia, and Ecuador, for example, you could live comfortably on a budget of less than $1,000 per month. I'd be surprised if you can't afford that.
