Im I being unreasonable?

Anonymous
Im dating this guy, we are both doctora so we both have to do nightshifts at our hospital, and he stayed yesterday. We are normally pretty tired the next day, but he told me we should hang out today. I asked if he wasn’t to tires and he said no, he was going to take a quick nap and that he should be fine.
We made plans to just walk on a park that is next to his house. I called him before going to the park (he asked me to call him so he would wake up) and I asked him again if he was tired to hangout, he said no so we made plans to meet in 10 minutes. He never showed up. I waited for an hour and I didn’t called him again because I figured he was too tires. About 2 hours later he called me and said he was sorry and that he fell asleep, but then he told me that a friend and his girlfriend arrived at his apartment and they were having a beer, that I should drop by (we live like 5 minutes from each other) and I felt a little sad and mad that he stood me up, just said “im sorry” and didn’t even offer to do something else with like grab a coffee or even pick me up to hang out at his place. He later called me and we talked a little, and he told me he was probably going to hang out with some friends of his. I just keep thinking he was only tired to meet with me but not to meet with his friends, but i am not sure if i am being unreasonable or not. It feels like he didn’t even care that much that he stood me up.
