The only reason I mentioned Spring Awakening was because the music seemed to suit someone around her age (college students). Even if he isn't a theatre guy, he may or may not like it.
I know the shows I listed are generally not the favorites of posters on this board (shows like Producers, Mamma Mia, etc.) but again, they might be shows your boyfriend would consider seeing since they are "fluff," and you would probably appreciate seeing anything.
Are you taking the Fung Wah/Grey Hound/Lucky Star? What's the earliest you can get there? Maybe if your lucky you can try Jersey Boys SRO.
