<human>: Throwaway account

My (first) boyfriend (26) and I (19 F) have been going out for a little over 2 years. The whole time we've been long distance due to him being in the military and my studies. We met online and live about three hours from each other. Since we are an LDR, our communication has always been a little lacking. 

Yesterday afternoon, I started having a heart-to-heart with him about how I feel that everyone has great expectations for me, but I always seem to fall short of them. He has always been the worst in my head for having expectations because I feel like I have to live up to his idea of a perfect girlfriend and he holds me up to very high standards. I've never told him any about how he has affected me until our talk where I told him that I was starting to resent him. He has told me before that this was one of his fears about our relationship. Since he is visiting home and had plans with a friend that night, all I was able to tell him was how I was starting to feel before his friend showed up to pick him up.  

We didn't speak until later today when I brought up that I was sorry for sharing my feelings with him as that wasn't the way or the time to do it. I should have told him in person. What happened next was that he acted like he forgot our whole conversation last night. When I refreshed his memory all he had to say was "Oh that. Don't sweat it" and changed the subject. 

I am very concerned that he just seemed to sweep my feelings under the rug, but I don't feel like I can confront him about it without nagging and making the situation worse. Should I bring it up again? How should I go about handling this situation?

Can you summarize the given text in a few sentences?
<bot>: I told my LDR boyfriend that I resented him. When I told him about it later, he just said that it was "No big deal" Where do I go from here?
