Don't want to fight with boyfriend, but I'm really hurt

So my boyfriend and I have been dating for 8 months and we have a great relationship. We don't fight very often, and we're very good at talking things out. However lately things have been a little tense between us. We've been having disagreements over little things. For example, he really likes to nap. Now this isn't a bad thing, but he seems to only nap when I'm over. Usually Im okay with it but some days I just really don't feel like starring at a wall for an hour while he sleeps. Today was one of those days. My boyfriend got kind of upset because he thinks I was trying to make him feel guilty for being tired and wanting to rest, but I assured him that wasn't what I was trying to do. I explained to him that it makes me feel kind of unimportant when he invites me over and then goes to sleep. This isn't the only issue I have with him sleeping. Every time I'm at my boyfriends house he usually falls asleep at around 9 because he claims he is extremely tired. So I leave and when I get home I FaceTime him because we're probably a little too obsessed with each other. Anyways the issue is, he always gets on his computer after I leave. Now this may not seem like a big deal but it makes me feel like he doesn't really care about spending time with me. He claims he was too tired to give me attention, but then all the sudden he is awake enough to get on his computer. I have spoken to him about how this makes me feel, and he apologizes and assures me that he loves me and I'm not unimportant to him. 
So tonight I was at my boyfriends house and we were watching a movie. It was about 8:30 when he paused the movie and asked me if I would be offended if he asked me to leave. He told me that he was just really tired and wanted to go to sleep. I didn't get upset over this at all because I understood. However when I got home, I FaceTimed him like normal, and he was on his computer. This hurt me a lot. I usually get a little upset when he does it the other nights, but this was the first night he actually asked me to leave. I'm not sure if I've over reacting or not. I think what hurts me the most is we literally had a discussion about how that makes me feel earlier today. I'm not sure if I should tell him how that made me feel or just try to ignore it and not start an unnecessary fight.
