HELLLP IDK WHAT TO DO should I choose my bf or my acting?!

So I’m in a play cause acting is my absolute passion and I love it. In the play I’m doing there is a kiss between my and another guy but it is purely professional and I have no feelings for him as I told my boyfriend a thousand times but m boyfriend keeps reeling me that he doesn’t want me to do this cause he feels like I’m cheating on him but I love him and I would never. He told me I had two options: quit the play and be with him OR break up and do the play. We’ve been dating for 10 months btw and I don’t want to lose him but this role is a really big deal for me and will open doors in the future HELP WHAT SHOULD I DO?!?!
