<human>: My boyfriend will act shocked and sometimes almost annoyed if I don't know something that he considers to be common knowledge. For example, if a song on his iPod is playing and I ask "Who's this?", he incredulously respond "You don't know who this is? Really?? But EVERYONE knows this band!" instead of just telling me the band name.

It makes me feel shitty, and stupid for not knowing.

He does this too often for my liking, maybe once a week. I've spoken to him about it before and told him how it makes me feel. He apologizes every time for hurting my feelings, but tells me that he was just expressing genuine shock.

It happened again recently. He brought up a current event in the news and I didn't know what he was talking about. I asked what happened and he went off again: "You really don't know what happened??" At this point I lost my patience and got up and left.

He later came into our room and apologized for making me feel bad, but the apology didn't really make me feel better because he tried to justify his actions anyway. He said that once again he was just expressing shock. That his friends will do the same to him when he doesn't know something, and that it won't bother him. That I'm really sensitive and it's exhausting to deal with.

Now I'm sitting here confused. Am I too sensitive?? I wish he would just explain things to me when I ask instead of making a big deal about it. But maybe he's not making a big deal? Maybe I'm taking things too personally? I don't know. :( What do you guys think?

Can you succinctly summarize the text in 1-3 sentences?
<bot>: Boyfriend acts shocked if I don't know something common, which makes me feel dumb. Am I being too sensitive or is he being a bit of a jerk?
