Is she a real whore or it's just emotions?

My girlfriend [f21] dumped me at 1st of April. We had a very beautiful romantic story and I [m25] was ready for anything for her. I’m from Russia and she is from South Korea. We met in France in medieval castle at July 2012. We were in volunteer’s camp. We repaired this old building. We were together all the time and failed in love to each other. But we both knew this is just moment romance so we don’t take it serious. After two weeks we finished the camp. I went to the Cote D’Azur and she traveled to Paris. We texted each other every day and I decided to meet her at Paris. We spent two perfect days at Paris and she went away. She desperately begged to meet me again and I promised to meet her at winter. We called and texted each other whole the fall and our romance became hotter and hotter every day. She became an exchange student at France so we set up a meeting at Paris. We rented the apartment together. Finally we met at January. We were the one. She prayed to me in Notre-Dame de Paris to be together forever. And then she offered to engage. I doubted but I made her proposal on the Arc de Triumph. Then we celebrated this in the “Ciel de Paris” restaurant. We were so absolutely happy. But our time was up and we parted again. I came back home and she went to study to Besancon. She promised me to come to Russia at summer. We discussed our family at February. But she became to visit party very often and drunk very much. At March she became colder with me but she still said that she loves me more than everything in the world. Finally she said that she need time to think at 1st of April. And at the same week she kissed with other guy and soon she said that she loves him and fucked with him. So now I'm terribly depressed. I don't love her anymore but I addicted of her. I know that I acted stupid to believe in feelings on distance but I wanted it so much. I want to revenge her. I'd like to know if she a real disgusting person or it's just emotions. How can I reduce my pain and would I get better if I'd revenge her. I know that "revenge is a dish best served cold". So now i have to wait and think what to do. What should I do?

I wouldn't get revenge on her. It's heart breaking and it's so recent it's hard. I know. The best thing you can do now is live your life, start doing the things that you love again and take one day at a time. Do you still call and text? If you do you should try your hardest to stop. It won't make anything easier, it's best to cut your ties with her until your heart heals. Out of sight out of mind..

I can't stop thinking about her. But I don't contact her. Nobody loves pity. I want her to feel my pain. I can't stand that person who make me so much pain just hanging out with other guy. My usually hobbies don't make be happy now. The only thing that I like she has become quite fat.
