How to get to the bottom of mr. virgo's feelings?

So I am a Leo lady, and began dating a Virgo man about 6 weeks ago. However, we really don't have the best timing. Since we began dating he's gone on several trips out of town, both for work and fun. He even invited me to drive up to one of his local trips, about an hr away for a night. I went, and we had a great time! He contacts me every day, usually by call/text. He's also invited me over to his house to watch a movie (he still lives at home), so I met his mom already. Things seem to be going great. He talks to me every day. It definitely seems like he is interested.

But I have noticed doesn't express his feelings as openly as I do. Getting so much as a simple compliment out of this guy is like pulling teeth! When we are out together he seems more open though, he shares a lot from his past. He gets back into town in a couple of days and will officially be done with all his traveling. Should I just wait till he's back to see if this goes anywhere? I just want to see him on a more regular basis, and I think he wants the same thing. Also, do Virgo guys have a hard time committing to an exclusive relationship? When I asked him what he's looking for, he replied, "Basically a girl who can be my future wife. I want to meet the right girl for me now, date her a while, then marriage." Judging by that statement, it's obvious he isn't looking for something casual. Right?

Thanks All!
