What OP should have done is express mild joking disapproval/dismissal of it, make fun of it in passing once or twice (NO MORE!), and then say that you aren't really interested in a long distance relationship. Boom, case closed. That's your stance and you won't budge because you know the reality. This is a woman. You can't reason with her, especially using arguments that appeal to YOU (fidelity, sacrificing her fun at the expense of your ego, etc).
Do you see yourself marrying this girl? If yes, then tell her you aren't interested in a LTR. If she sees you the same way she will respect that. Not seeing marriage down the line? OK, say you aren't interested in a LTR and break up with her and find someone new. TRUST ME: Women will find it attractive that you dumped her when she was about to leave. It might be hard for a week or two, but trust me, you'll be having a great time soon enough.
It seems like she has made up her mind. What someone in OP's shoes has to do now is simple: surround yourself with friends, live your life, work out, build your relationships.
OP's girl has made a willing exit. Telling her how badly her exiting is hurting you won't do shit. Begging her to stay and implying you care so much that even though she's halfway out the door you will still be waiting for her when she comes back won't do shit either. You are a man. Be proactive. She'll do what she wants... so let her know it's a dealbreaker. If she leaves she leaves. Congratulations! A new chapter of adventures has opened up in front of you.
