history: I once accidentally called my girlfriend by my ex-girlfriend's name.  I couldn't believe I made that mistake. I accidentally called my girlfriend my ex-girlfriend's name. whoops_comma_ lots of people have done that. what'd she say?
current: I was ashamed. She yelled curse words at me.
next: hopefully you were able to work it out...if not...in the future don't tell girlfriends about exes.
