<human>: I [20 M] met my girlfriend [20 F] almost a year ago. We fell HARD for each other. At the time I was not enrolled in school and she was on her way to New York, so I followed her there. 

It's been quite clear that I've been the emotional glue in our relationship, and that all efforts to maintain it's existence through really hard times have been mine. Having said this, she has been and continues to be single handedly the most positive person I've let into my life. 

There's just one thing--I hate New York City. It is by far my least favorite place to live in the U.S., and I have lived in A LOT of different parts of the country. 

A situation has risen where I have an opportunity to live in Santa Clara, CA (a city I have lived in before, and loved) for free and attend school for very little money. She won't come with me. 

I am at a complete loss. If I leave I know that I'll always regret not keeping her close. If I stay I will live in the despair that's been my New York City living. 

Help; I love her

Can you condense the text into a few key points?
<bot>: Went to live in New York City with my girlfriend and I don't like it: should I stay in New York or should I go?
