not taking it anymore

this bitch was suppose to pick me up and go to a get together with me and my friends. He calls and ask if he can meet me there cuz he had some errands to run first I said "Okay I'll see you later tonight then" I don't hear from him at all then I see on snap he posted on his story "going to the movies who wants to be my plus one". I got so mad I screen shot it and sent it to him under "Seriously!" he hasn't messaged back yet but it doesn't matter what he has to say I'm done
