Am I don't something wrong?

My boyfriend and I have be fighting a lot lately. And it over little stuff. I feel like he doesn't wait to be with me and I don't want to lose him. I don't know how he feels cause he doesn't communicate with me. He works all the time and I understand that, but when he's with me, should he focus on our relationship and understand me it the time we share? Am I wrong for wanting him to spend more time with me? I feel like I'm the bad guy in all of this. I just want other people advice and give me suggestions on how to fix things. I really do love him.
