From my experience most males are much less expressive in the verbal sense than women are. He may be an introverted personality. Which is fine, but if you need more conversational stimulation, you may be headed down a road that you won’t want to stay on.
But the way you’ve described him so far, he sounds wonderful, and the fact that he actually does talk on the phone with you for long periods of time and you seem to enjoy these pleasant conversations, then there is hope.
My S/O used to be quite shy, mostly around everyone else, and kind of still is, but I am a pretty good conversationalist, so he is pretty chatty with me. But I’ll tell you, some of our best conversations are not about politics and art and the state of the union. They’re silly stuff, inside jokes, talk about TV shows and movies that we’ve seen, restaurants that we’re going to try, how douchey certain politicians and television personalities are etc. I know exactly where he stands on religion, politics, child raising, animal welfare etc. But that is because I’ve asked him, and then told him how I feel. But I’ve never pushed my beliefs on him or demanded to know why he thinks the way he does. I’ll just ask him, very gently what he thinks about this or that.
Sometimes you just have to (gently, not forcibly) ask lots of questions and demonstrate by example how you explain (out loud) what you believe. I think a lot of people know in their heart of hearts how they believe, but they’ve believed that way for so long that they don’t even think about why they believe certain things. It can be a little awkward at first for people (especially young people, and especially males) to think about their beliefs, then come up with an articulate verbalization of those beliefs.
But as long as you don’t bark at him, or demand answers, but just gently ask a lot of questions and give him plenty of information on your own beliefs and why you hold them, then he will likely jump into the discussions more and more as time goes by. That’s how it turned out with me and my S/O.
If it turns out that your new fellow has some very different (or opposing ideas) to yours, that might be an indication that you guys are not as compatible as you would have hoped. But on the other hand, there are probably plenty of jellies in here, who have S/O’s that are on the other side of the political or religious spectrum from themselves, but they are able to cordially and respecfully differ on those things.
The love and the like and the desire to be with someone has to outweigh any of the perceived negatives or shortcomings. Also, one person cannot be all things to another person. So you may be able to have a perfectly wonderful, loving relationship with this guy and get some of the other stimulation from friends and relatives and colleagues and teachers.
So give this guy some more time, but practice asking him more direct questions (without coming across as hostile or demanding) and let him know from where you derive your beliefs about all sorts of subjects. He may pick up on the conversational style.
An example conversation:
“You know John, I really love having all of the modern conviences of life, but I often worry about the cost of these conveniences. It concerns me that our dependence on oil is going to ruin our country down the line. If you were the President, or were in some type of position that you could change things, what would your approach to our energy problem be?”
If he says “I don’t know.” Then you need to make another statement and then ask another question like, “I think we need to make some major changes. Do you think it would be a good idea to give tax incentives to entrepreneurs who develop new energy techniques? Or do you think it would be better if we just drilled for more oil in our own country? For me, I think the new ideas route would be more cost effective and efficient in the long run. What do you think?”
