I think the song is about struggling to find a partner in life. After a while it feels hopeless.
He compares the feat of finding someone or making a relationship work to climbing a mountain (volcano) and the act of the relationship itself and "opening up" to the other person as diving into it. "Born to dive" shows his propensity to take risks and trust and open up to people, and how it inevitably backfires.
