<human>: Hi, I have an issue with my bf's behaviour and I'm not sure if I'm being reasonable in it or maybe overreacting.

I am 22f, he's 31m and we've been together for 9 months. We're not living together. He has his own flat and I live with my parents.

Last week he was sick and he took a day off from work. I am a student, and I had a day off school too on that day. I could've helped him, cooked for him and so on, if he just told me. Anyway, I wouldn't do it if he wanted to stay in bed alone, that's also ok, but he didn't tell me about this day off until I called him, because I wanted to pick him up from work. I just felt upset that he didn't even consider telling me what he's up to, especially since I told him to let me know how does he feel and if he needs anything.

Yesterday, I left his flat in the morning, I went home and he was supposed to go to his family for dinner and then come to my place at 6. And then 6 came and passed, and at 8 I texted him saying "thanks for standing me up" to which he replied "I'm sorry. I spend too much time at my parents' and only now I'm going home. Kisses." I was pretty angry, because he behaved like nothing has happened and that's not true from my point of view. I waited for him those two hours, I could've do something else, go out or whatever. And then I just get "sorry, kisses" like it was ten minutes. It's ok if he didn't come, but just tell me about it. I feel stood up by my own bf. I thought this happens only up to first three dates.

It hurts me that he doesn't even think about me when it comes to situations like these. He doesn't consider me in his plans. I don't know if what I feel is reasonable, maybe I'm overreacting? I even thought about standing him up, but that's just stupid and childlish (and passive-aggressive probably).

Provide a brief overview of the text.
<bot>: Bf stood me up on a date/meeting and only after me contacting him he cancelled our plans. Am I being right in being upset about it?
