Date abroad works really well at the early time of internet, like 1999 when we have internet and people start to use it for basic communicate like chat and email, it's something new and replacing for tradition communicate like phones.
Later when the time move on and digital come out, it's giving more choice and advantage but also brought in more trouble and kill your relationship. People get stuff more easy and don't treat it with respect. Okay, if you're dating abroad for example you're living somewhere from Europe and dating a hot blond American/Canadian girl, her age around 20-35, okay you want to moving fast with your girl but the distance and technology may kill it,
the scenario is your girl has a lot of things to deal with like, social relationship, facebook, smartphone... take away her time and giving her more distracted, something not happen from the 90'.
