Should I be mad? Need advice

So my bf and I got into it because we were supposed to pick up a bed today and I had told him about this a few days prior. Earlier today I told him we were going to pick it up around 5 then around 4 his friends call him to come and drink with them and i told him what about the bed you’re supposed to help me. He then continued on to say no he wants to have fun with his boys and that he never gets to drink when he did drink last week. He said he would help me and then he cancelled on me to drink with his friends. I’m so pissed because he told me he’d help and then he cancels on me for his friends. Should I be mad?
