"She then took a offense to me saying "bandwagon" (I know, petty) and started to flip saying things like "Hold up chick, I was NEVER an Eagles fan so I'm not on no bandwagon....""
It sounds like she doesn't understand what a bandwagon means...
And her jumping to the old stuff is EXACTLY why I do not EVER talk to my IRL friends about stuff with DH! Heck, I'm still annoyed at how a friend's husband used to treat her, meanwhile they've been married for ages and she's happy, and the stuff he did was no big deal at all. Let alone if a husband had done something really bothersome and beyond!
If you want to be friends with her again, time will help.
If you don't want to, time will help, and at least you had the conversation with her. Though if you don't know WHY she did all that, it might bug you. A friend dropped me, oh, in '97 or so, never told me why, told outright lies to mutual friends about why we weren't friends, and I'm still not totally over it. I never got that "why?" conversation. But I was the last of the female friends from college that she dropped...thought I was safe but I wasn't!
