Would you be upset?

My boyfriend of 5 years recently made a new group of friends and invited me to hang out with them. I thought we had a great time but the next day my boyfriend was acting very distant. I asked him what’s wrong and he said his friends don’t like me because I didn’t smoke pot with them and said I’m not the type they’d be friends with. My boyfriend is a pot smoker but he always made it clear to me that it wasn’t a problem that I wasn’t into that scene. He never pressured me before and it was never an issue. He said it’s important to him that his new friends like his girlfriend so I need to either smoke with them next time or he will have to reconsider our relationship. I told him I’m not changing who I am to please him or his friends, especially ones that came after me. He said I’m being insensitive to the fact he really likes these guys and wants the friendships to last. I told him that if he’s being serious I will leave him right now because my future husband would never expect me to change who I am. I said I would prefer he didn’t smoke but I never made it an issue because I love him for who he is. He got very angry and called me a boring bitch and stormed out of the house. He was gone all day and didn’t come home until 4am. He was drunk and peed on my work clothes that I had to use for a meeting the next day. When he woke up he profusely apologized and said he was wrong but that he was just embarrassed that I didn’t fit in with his friends. Would you be upset?
