The girl is upset that she can’t seem to find long-term companionship. She loves to travel, and suggests that all girls should travel abroad at some point in their life, however, perhaps she has done so too much. She has traveled abroad to escape her life in the past when long-term relationships end, and she wants to go back, but can’t bring herself to do so.
And because she can’t, she can’t start anything new with anyone else either. She has even tried, but most of the people she meets are in places temporarily and are not looking for long term, and this is weighing on her psyche more and more. She tries to play it off and go with the flow just to have some companionship, but in the end, it is eating her up inside.
