Am I overthinking ?

Hi

So i’ll be straightforward, yesterday my bf and I decided that we will meet today ( he mainly wanted to have sex ) today he cancelled saying that he’s sick and got a flu, 3 hours later he sends a video of himself going out with his friends i was like you were just saying that you’re sick and cancelled our date that you’ve been asking for for days????????( I was saying this to myself lol ) anyways, Am i right for being mad? We haven’t talked since he cancelled tho.
