I thought he loved his wife...
Just watched this for the first time in nearly 15 years. I thought this was spposed to be a love story. Bobby wants to be with his wife. When he was Billy, he had no problem sleeping with multiple women. I get that a menage a trois is every guys fantasy, but it isn't really apropriate here.
FYI, I agree with the previous poster, I always thought Bobby looked like Rick Springfield.
