to me, this song is about a very young couple in a relationship and the girl gets pregnant. they get married even though the guy is uncomfortable with it ("the priests were all stoned" because they were encouraging them to get married; but he knows it was a mistake because he doesn't really love her "love was a game that we played"). "california was in my mind" and "my head's in the ground" because he wants to run away from what he's done, while the girl truly loves him and is hoping they will stay together, especially because of the pregnancy ("everything is fine, now the baby's here").
