I don't know what to do

I love my boyfriend. I do. But we haven't said "I love you" yet. Well scratch that. We have and then 2 weeks later he said it was too soon. It was 3 months. But anyways now we are almost at 6. And I know it's too soon to be even talking about marriage. But I would think at this point and at our age, we are too consider whether or not we are planning to marry this person. I'm in this relationship for potential marriage sometime down the road. But when I said something along the lines of getting married in the far future he says stuff like "it complicated". And I respond with "well I want you to want to marry me, I want someone who wants to marry me" and he doesn't really respond. That's how tonight ended. I'm a little sad. I think we may break up because I think he thinks he is not capable of loving anyone. And I do deserve to be loved , and seen as someone's future wife. Idk. I do not want to break up. But the lack of love and faith in the future hurts so bad.
