Stiffen you backbone,get in your car and go get your stuff from her place.Do it NOW before you talk yourself into some dumb belief that she has the slightest regard for you.This little lady is not into even the mildest form of courtesy,honesty, decency or commitment. She is just hanging out with the guys and that is what she wants most. She will probably try to keep you dangling for a while longer so that she has a fallback date on Saturday night, but her actions say that she not your girlfriend -not even close. Bail now!
