This makes me think about a boyfriend I had in my mid 20s. At the time we met, he was way more into me than I was into him. But we kept running into each other until he grew on me and we started hanging out. I was surprised to learn he was already divorced having gotten married basically right after high school after a couple years. He didn't really tell me much and I didn't ask the questions I should have; but the understanding I had was that he had been totally in love with her (his words) and it was she who broke up the marriage.
