^ That is also why you see a lot of people blaming robb for everything that happened.
with Talisa (show) not being in the picture, it takes off that rose colored love story we got, and showcases the real bad decisions robb made. also how his mom tried to stop them each time.
This is why I enjoy Catelyn's chapters (which is pretty unpopular to people 1st read through). she did something really irrational with letting Jamie go, but was also very strategic, a lot of her advice was strategic, but also honorable. more so the way Ned would've done it than Robb
