Am i wrong?

Hubby is furious with some stuff going on with his school. Long story short he was locked out of his online classes because of a mistake on the schools behalf. He called yesterday and they agreed to fix it. He got a call today saying he will fail if he doesn't do his assignment today. (Keep in mind he was just allowed access to it a few hours ago and is at work until 6). Without going into too much detail, his school is being completely unreasonable. Soooo he calls me while he's at work to vent. Totally fine with it. I was there, let him talk and reassured him all will be well after tonight. He comes home for lunch and begins telling me the same story from the phone call....again I listen, reassure him and even offer a little advice. We finish lunch and the begins to tell me AGAIN. At this point I'm now irritated this is all we've managed to talk about and he's repeating himself for a 3rd time. I look at him and say "baby, I know" & he becomes infuriated I won't listen a third time. I know he's upset but if I were repeating myself I'd want to know. I'd also want someone to say something if they didn't want to hear the same story over and over. Then he trys to make me feel like an ass for saying something instead of just listening.
