Boyfriend having doubts? I think it was my fault.

[Jonathan]

So last week my boyfriend and I were talking and he admitted he is having doubts. To get into more detail. We are going to hit our 6 months. Which is a milestone I think. I kind of told him I wanted to know if he was 100% in or out. I think that scared him because during our talk he says he loves me, and would be heartbroken if he lost me, but he is not ready to make that decision. Was I asking to much? I never said get married. But I just wanted to know of there was a possible end. He said he is scared because he is 20 and this could be his last run at a relationship. But he wants me. He says every day he loves me. It's almost like he gets doubts when we are apart.
