normal to be so annoyed with so?

idk if its the hormones or just his plain stupidity but sometimes I really wanna strangle my so. I haven't eaten all day and he invites his friend over and I can't eat in front of him because it's weird and rude and so now I'm sitting here starving to death waiting for his friend to leave. I'm so fucking annoyed it's unreal. I'm on the verge of tears because I waited on his stupid ass to eat dinner which I know I shouldn't have but I hate not eating with him, but I did trying to be nice, and he fucked me over saying he was just going to grab something and he was gone over an hour. I. just. want. to. eat.
