“My boyfriend thinks I was on a date”

Hi, I have a question. Is it wrong to eat out and watch a movie with a good friend, which is a guy, even though you have a boyfriend? Does that pass boundaries? Because my boyfriend got totally pissed. He’s aware that I was going to eat out with my male high school friend.. but he got pissed when he found out we were going to watch a movie, where he perceives the situation as if it was more of a “date” then a “hang-out”… Help!
