Emotional Wreck...Please help?

My boyfriend and i have been together for 2 years. Our relationship has been rocky and he is unsure about our relationship. We both have made our share of mistakes. He doesnt call me as often as I'd like, so I find myself texting him and making the effort. I found out recently that hes been distant because his parents had the talk about marriage with him. Im not sure what the issue is that was brought up, because hes reconsidering our relationship now. His parents arent aware that we go out. We are going to discuss our relationship soon. I think he doesnt want to commit to me without clearing things up since we havent had a smooth relationship. I'm really scared. I love him alot. I am away from him for 2 months. I just want to be in a normal relationship. Im scared about what hes going to bring up and what parents said to him. How should I react if he ends it with me? I'll be devastated. Any advice?
