Try being in a long distance relationship. Try listening to her cry, but don't hold her or kiss her, and text her to comfort her, because you're literally 1,000 miles away and that's all you can do. Try seeing her over Skype and only Skype, where sometimes the call drops and the quality isn't great. Or how about planning a trip to go see her? But wait you can't, because you're having financial issues. Try explaining it to your friends, try telling them why they can't meet her. Don't even think of planning dates, because you'll be the only one attending them. Try fighting with distance, that shit isn't easy because you have distance on top of it. Try sleeping alone every night after hearing I love you and cuddling with a stuffed animal that doesn't even do the trick because you know it isn't her. That's the really hard type of relationship.
