Mad but not sure if I should be

Me and my sneaky link made plans to see each other spoke about it the day before and the day of. I messaged him to let me know when I should come then says he’s too tired now I’m sitting here like WTF😡😡😡😤

I know you work full time everyday ppl get tired I understand but you could’ve let me known. I’m sure if I didn’t message him he wouldn’t have said anything probably would’ve still been waiting

Am I overreacting being selfish or is my anger valid ??
