at that point i guess she already knew were things were going to end up, this is not a fact, but something i assume, whenever she got those "unfortunate health news" im assuming it was that her pregnancy wasnt viable, so she wouldnt be able to carry it the whole way, and all of that time, going to the doctor pretty much every other day, she was just waiting for the inevitable, and when it finally happened, given that eric didn't really seem to care, and he also brought angela to atlanta ... i guess she decided she was done.
