Guy advice

So I've been talking to this guy awhile. He respects that I don't want to have sex yet and motivates me in everything I want to do. He talks to me every day and we see each other at least once a day on his linch break or at night. He says he really likes me and would love to be in a relationship with me one day and maybe marriage. What do I do? I want 5 settle down but kinda nervous
