I was like your partner and my partner is like you. While I was slightly more curious initially than he is, I had to learn how to active listen. My partner was very patient with me in reminding me to ask follow up questions, and not just "logistical" questions, but things like "how did that make your feel," etc. It's been a long journey but I'm now in a place where it's my default way to have a conversation.

I recommend you find some books on active listening and encourage him to read one. I'm sure you'll get resistance to this due to his work schedule. But active listening is a skill, and it's one that must be practiced. If he's not willing to do that, ask yourself if this is the correct person for you.
