Things are at a lull with my boyfriend and I and I'm not sure what to do.?

I'm happy with my boyfriend and he says that he is happy with me, but I guess I just miss the way that he was when we were in our "honeymoon phase." I miss getting that little bit of extra affection from him and hearing him tell me how he feels about me. Does he know do that know because he umes that I know by now how he feels? I know that he is always super busy and stressed with work and with his athletics for school and everything, but too me I think what's the point of having a girlfriend if you aren't going to make the time for her. He makes time to hang out with me but it's like sometimes we are apart for so long that it would just be nice to hear that he misses me and cares about me. So what should I do? Am I just being whiny?
