Help? Husband dilemmas.?

I have been married for almost 2 years now. He has always had a bit of an issue with telling me what he is going to do for that day. We make plans to go have dinner. I'm so busy with grad school and work so any little time that I spent with him is good. Today we have plans that we would go to my school together and have dinner on my hour break. When I get home, he said that he was 45 min away with his friend trying to get a job. He had promised to go with me, but he said he'd meet up with me later. Because he doesn't have a car and my school is an extra 45 min away, I thought it was impossible for him to come. He tried to come visit me, but was unsuccessful.

I am very angry at him, so angry in fact that I am questioning my whole marriage. He knew that this was my pet peeve and he is still doing this to me. I hate flakes and I'm starting to really dislike him. I told him that I hate him because I'm angry and I don't want to put my all into this right now. I know he's having a hard time because he lost his job, but I am mad at him for doing this to me.

My question is: Am I right on being angry? How can I move past this? I had a 13 hour day from work/school and I can't sleep because I have a horrible headache. I want some peace tonight and I don't have anyone that I can confide in right now.
