Don't underestimate how much influence your behavio(u)r had on his actions. There were a lot of "I don't knows" and such in his explanation. All along he saw a safe haven to return to, even if he didn't realize it. He saw a strong, capable woman. He saw that the grass wasn't greener. He's not going to remember individual events, or things you said. But there were feelings that you allowed to grow.
DBing is a tricky thing. I don't think it's a sequence of events, of actions. It's an attitude, and a way of life. It's impossible to say what would have happened if you had not been DBing, but I'm guessing the outcome would not have been as positive for either of you.
