If he realized that I couldn't fall in love with him, but I thought I was, a betrayal when he wanted to marry?

1 1/2 relationship just ended. FOr many reasons. But the main reason is I had so many issues, I guess I never fell in love with him. I thought I was, and feel like I love him now. But when I look back my actions seemed like I just was unhappy with my life and couldn't give him enough back when he gave me his heart and soul and tried extremely hard to make me happy. My mother says that he probably feels like it was betrayal. Even though he knows I had issues and didn't do it purposefully. He is so absolutely upset, he feels used (which I never did on purpose, I have just been so badly burned it was hard to let go completely 24 hours 7 days a week). And again I didn't realize what was wrong with me. He is so hurt I want to know that in months time he fill find a way to forgive me. What do you guys think? If I truly decide he was the one for me, could he ever trust or love me again? He really wanted to marry me, and did every thing he thought he could to make it happen. His ego is so hurt and he acts as though he hates me really.
