Continental Rift

Let me just vent here because I have no other place, so my gf and I were together last year and everything was fine, then she succeeded in nailing a paid studying program in another country, yes I am rooting for her and everything, but now the relation transformed to a long distance and in a year we could meet only one week in the whole year, and things will keep going this way another 3 years I suppose, I promised her marriage before and everything but things is getting rough for me, how fo marry someone who is not with me, and how to marry someone who will be present only a week per year.

Another context also, I don't like to mention to her but its eating me from inside sometimes, when she heard the news about the studying program she called me to ask me and everything, and with joy she told me that her family are happy and everything with this, so it was apparent to me that they already decided that, and I didn't want to come against her choices and her family happiness about the success of their daughter, but then she kept saying to me, that everything would be the same huh , I've said yes many times, but It felt like I was asked about my opinion as secondary, and that even if I refused I would be ditched away that moment, and now I see the repercussions of the distance, we keep calling each day, but I dunno.
