When to get married in my case?

You know that feeling that you just have after being around the block a few time and acually meeting him? Well I’ve been dating Brad for almost about 9 months now. I feel for him just like I did the first months that we were together. I have a promise ring on my finger. he has a steady job. I’m just finishing up school and about to go to a trainy school for my occupation. I still live with my parents but brad has a place of his own. he is 20 and I’m 19. I know that we are young still, but age really has nothing to do with stuff. I personaly think that its how your life really is and how mature you are in the making. He has been talking about marriage…and I feel like its right. I used to freak out from a commitment phase…but not this time. I acually think that it feels right. There wouldnt be kids untill farther down the road. We’ve both talked about that and also …we wouldnt get married untill about a year down the road untill I’ve started a full time job with my occupation that I’m going to college for. Do you think that I should tell him I am ready for a deeper thing between us?
