Carrie gets her heart handed to her in season two when Big announces he may or may not be completely abandoning their relationship to live in Paris for six months. It's awful, and it's one of the many times we wish we could just grab Carrie by the shoulders and tell her to get some self-worth. Luckily, she begins to learn that lesson on her own (and with the help of her girl gang), but it is still very painful to watch. It's iconic because it's so relatable, and more importantly, it's an extremely valuable lesson all women need to learn: you have to stand up for yourself. Oh, also, Charlotte starts getting free shoes for her relationship with a foot fetishist, and her internal struggle with the exchange is absolutely hilarious.
