You could ask him for more information. "What do you mean by 'figuring it out?'" "Is there anything you can discuss with me? Maybe you have some questions I can answer, or beliefs I can respond to?"
I'm not sure exactly what he's trying to "figure out" so I can't begin to guess whether he actually is trying to do that. People behave in all kinds of ways when their thoughts are in termoil... his behaviour could mean one thing in one person, and the exact opposite in someone else.
I prefer to give people the benefit of the doubt. If he says he's trying to figure it out, then he probably is. That being said, "figure it out" is sometimes code for "I don't want to get serious, but I don't want to say so because I worry that then you'll never talk to me again." So... it's anyone's guess, really.
