Am I being ridiculous?

So today is my two year with my boyfriend. It is a Monday but neither one of us have school. Yesterday I said "what are your plans for tomorrow?" and he said "hunting in the morning, then work at like 2." and I said "oh. okay" it almost seemed like he forgot. then after I said I wanted to go he said "I know tomorrow is our 2 year. But I have plans." (Hunting and work). I was unaware of these plans and thought maybe we would see each other at least for a little bit. (By the way he works from 2-8) I'm talking about before he works maybe we could see each other. I didn't tell him I was upset. But I am. Am I overreacting?
