<human>: We both live in 2 countries very far away and have been doing long distance for nearly 3 years now. I have been in her country for the past 3 months as she prepares to move out so we can be together. 

Last night we went out and got into an argument. She wanted to continue the night and go out. I however wanted to go home. So i decided to go home and she left me in the cab and would not give me the keys to get into the apartment. Its -30 and i had to buzz random apartments to let me in. She returned after 2am when the bars had closed. I sat and waited in the foyer for over an hour. 

There is nothing inside of me that could ever do this to her. Knowing she was stranded and by herself i would have never ever left her by herself like that. 

I told her I'm flying home earlier than expected as that was way too much for me. 

We dont live down the street from each other so a goodbye is a goodbye forever. We can't patch things up once i leave. We can't talk about this in a week when its cooled off. I feel absolutely sick to my stomach. I love her with all my heart but am so hurt. 

Please help with any advice
