am I wrong for feeling this way?

I'm upset... My boyfriend has lied to me about a promise he made, but I never brought it up bc I knew it would just bother him, and he would just lie again about how he wasn't lying. I don't know what happened, but I finally brought it up and he sounded upset, and I just started apologizing for upsetting him and then I started to open up more about how I feel, and then he just started changing the subject. 
Am I wrong for being bothered about this? I actually started opening up to him about how I felt for months, but he just seems to ignore it... Maybe I'm just over exaggerating, I usually start problems anyways when ever I talk about how I feel...
