<human>: Hey /r/relationships :3 

I've been dating this guy for the last month officially, but seeing each other tons and dating and what not for a month before that too. He's really kind, sweet, funny, all that. We spend quite a bit of time together and I appreciate that since the last serious relationship I was in was long distance, this fella lives right around the corner from me! When we first started talking he was very open about the fact that he's an introvert, very very introverted, and I understand that because I used to be as well. Not sure what happened, but I am much more extroverted now (which works for me, it's good to understand both ends of the spectrum). 

We have gotten to know a bit about each others pasts, personal lives, all that, as is to be expected when in a relationship, but what I have neglected to mention (because it serves no purpose to him - to be said out loud) is that my one real relationship before this one, the guy and I were both extroverted and open with our feelings. It's hard for me sometimes to figure out how J (that's what we'll call my current BF) is feeling. I ask him what's on his mind, he says nothing, I leave it be. It's never in a fighting or arguing situation, haven't had one of those yet, but just if he ever goes quiet for a prolonged period of time I get curious. 

It probably sounds silly, or maybe doesn't even make sense, but I guess what I am saying is that I'm used to there being more of a shared excitement and openly so. 

Does any of this make sense? I'm a huge rambler. Just looking to see if anyone can help me understand emotions in a relationship from introverts and how (if at all possible) I can maybe get him to open up slightly?

Could you distill the essence of the text into 1-3 sentences?
<bot>: I'm extroverted, I share my feelings, he's introverted and keeps lots of thoughts to himself. What do? Leave it, or perhaps talk about it?
