I have a guyfriend who invited me to go to prom with him. It's just a friends have fun thing. I also have a boyfriend (me and my boyfriend are already out of high school). I just want to go to prom again because its so fun. Do you think my boyfriend will get upset if I go to prom with my guyfriend? I know he will let me and say "have fun!" but I still don't want him to get upset inside. So, whats the best way to let him know.
