His relationship with a woman was complicated by drug use and they split. He's moved on - "almost grown," and wants to get away from that lifestyle. She's still in love with him and has tried to quit - she's "come across the snowy" fields to see him. But it's not working for her. He still has feelings for her, but he's torn between Boston, his past, and San Francisco, his future. I guess he ends up in Boston again.
