1. How much money and time do you want to spend on traveling?
When you really like someone (dare I say love?), you want to see them a lot more than just once a year. Most people don’t have the budget for more than one or two major trips in a twelve month period; if you’re a free spirit traveler and adept at hopping Greyhounds for 52 hours straight, or finding the cheapest courier flight to Thailand, good on you, although you’ll still have to shell out for visa fees. But most other people have limited budgets (and, if you have a regular job) vacation time. All of your extra money and time will be spent visiting your partner. That’s not a joke or an overstatement; you are going to want to see them, and you’ll be willing to forego luxuries to scrape together the cash for yet another flight to Luxembourg. They’ll be able to come to you sometimes, too, of course, and you’ll rack up a ton of frequent flier miles if you can keep your tickets all on the same airline. But, honestly, a long distance relationship is time-consuming and expensive, and eventually most of your conversations are going to deal with how one of you can move to where the other one is, or you can both move to somewhere new…or how you should break up because you never see each other.
