Confused and need help and advice!!!

Ok so this is going to be a long one... So I am engaged to someone that is 25 years older than I am and we have been together for a year in Sept which is when we both decided to get married. I know all relationships have its ups and downs but what about when we are around one another, we really don't talk but more or less do more arguing. We work together as well but while at work we have more convo with our co workers than one another. And how about the fact that he once introduced me as his friend instead of his fiance to someone at a church event we went to... And what about our intimate time, we don't cuddle or hold hands or anything like that... He would rather just dive in and that's that... When we are home, he spends more time outside than inside with me... I really love him and I want this to work but it doesn't look as he wants any of it... When I try to talk with him, he has nothing to say or he gets mad because I bring it up... I don't know what to do. You would think that he would at least be man enough to come out and say that it isn't working for him and he just wants to be friends, but he doesn'tsay anything. What should I do? What would you do? And on top of it we have been talking about getting pregnant... Am I just going crazy or is he just not that into me?
