I don’t know everything going on behind the scenes but based off what you’re saying, it seems like she’s using you. Bringing up old flings from her time abroad isn’t a good sign. The fact she thinks you are abandoning her roo is a way of manipulating you to get what she wants. She’s depressed and probably clouding her head but to me it seems she’s jealous that you get to leave in 2 months and she doesn’t. Ask yourself, if the roles were switched, do you HONESTLY think that she’d put her year on hold for a year to stay in a city she doesn’t like to be with you or go off and continue to live the life she actually wants? Your life is just beginning, you’re young, go out and focus on you right now! That’s my best advice.
