Never initiates contact with me but seems interested when I initiate contact. Does he like me?

Anonymous
I asked him out (for a few weeks from now) and he said yes, and he gave me his mobile number (I didn't ask for it). We've been texting since then, from 5 mins - 2 hrs conversations, but I always send the first text message in any conversation we have. He is happy to answer almost any question that I ask, including personal questions. And sometimes he apologises for not texting me first, but he never does text me first. I'm not sure if he is just being shy, or if he is unsure how to start a conversation - he is like that in person, but I thought he might be different over text message. Sometimes he sees a message then takes hours to reply - but he will apologise when he does so and explain that he was busy. Anyway, at the moment it feels like I'm doing all the chasing and I want to know: how can I tell if he is actually interested in me?

Extra info:
He has only had one girlfriend before, and he was with her for 3 years.
He has been single for the last 2 years and I have known him for about a year now.
I know that he is only interested in dating for marriage and that he doesn't do casual dating.
He isn't that interested in you
He likes you but shy and/or socially awkward

Should I just keep talking to him and expect him to gradually start conversations with me?

Actually, I saw him tonight and he looked at me so tenderly that I'm sure he does like me.
