When do you NOT stand by your man?

I'm so very sad about my
boyfriend. How does a woman stand by her man when he makes a choice like
I'm not and never will be a Jeff Gordon, Jimmy Johnson fan. What will I do? Who will I love now? I can't have lust for a Hendrick driver. I like Tony Stewart, but I don't like him ,like him, he's nice and has a good personality, but not boyfriend material.
I could have forgave him for going to Joe Gibbs Racing or even RCR, but Hendrick...The shame of it all.
I think Jr and I will have to break up at the end of the season, I'm gonna start playing the field, he has broke my heart *sigh*
