<human>: Condense the text into a few key points

3 month medium distance relationship (1.5 hrs away), I think things are going well. She has been going through some hard times lately, but I've been there for her.

She worked cochella this weekend, and things felt distant. Less texting, etc. She's also been busy though.

We talked briefly yesterday afternoon, and things felt wierd. She said she would call at night.

Instead I received a recording of a song she wrote, calling me her "golden hearted boy" and bidding me "goodbye". Or at least that's how I interpret it.

Now she isn't returning calls or texts and it's driving me crazy.

Was I just broken up with by song? WTF?

Should I drive 1.5 hours to her house to figure this shit out?
<bot>: Girlfriend sends me a song she wrote which I interpret as a breakup message. She won't return calls or texts. What do?
