M. Chazy_Chaz, if you two love each other and you two trust each other; if you've built up a solid foundation for your relationship; and if you two truly believe that no other person can make you as happy as you are with each other then I wouldn't worry too much about going abroad and leaving her here. Besides, if both your parents approve of your relationship, they can also support the two of you in this difficult time.
And if you want to see her, that's why God invented the Internet, remember? You two are going to be an online service and a click away. Of course, if you want to get really romantic in an old-fashioned way, there's always the postal service.
Trust her and trust yourself; in the words of Jon Bon Jovi, "Love is just another word for 'trust'."
Vaya siempre con Dios and good journey, sir.
