Just don't get it ..

After last night, I figured the way things would be between us would tweak a little bit. I mean, not completely change but just tweak. The way we handle our issues. I did a good job so why can't he? I know there is something on his mind thats bothering him but he won't tell me. He would just push me away. How can we grow if he won't talk to me? I really just don't get it. We are suppose to be the perfect couple that argues and then talk about it. That's how we wanted to be and it happened for some time but not all the time. I wonder if its me. Am I doing something wrong? I just don't get it.
