Totally agree. That's why I initially loved the show, their POVs, seeing the differences. Their chemistry is amazing. You could see how much they felt and understood each others pain. In a way only the two of them can. I love how Cole really does unconditionally love Alison, and he really does accept her and her flaws. He sees the person beyond the mental illness and bad choices. Cold said as much last season, before Joanie was presumably conceived, that he sees Alison as a valuable person, and understands her pain. Yes, she is depressed and anxious, probably dealing with PTSD, her mother leaving her at a young age, etc. Cole had been dealing with depression and family issues as well. They both make bad choices, and have regrets. Life is like that, it's full of grey areas, emotion, miscommunications, timing, personal growth, selfish choices, searching for happiness, etc. I feel like their storyline is realistic and compelling, seeing how two people manage life after a trauma, and how there is no perfect ending, no perfect choice, it's complicated, their are consequences, and people will inevitably be hurt.
I have empathy for Alison, probably because I have struggled with loss, depression and anxiety as well. I have made choices and done actions I regret as a result of that. I have had ups and downs. I have had chaos in my life and in relationships despite my best efforts.
You can almost see Alison physically suffering under the weight of it all. She is trying to improve herself, to be a good mom, to be present, etc. Does she fail a lot? Yes. Make terrible choices? Yes. We all do, some more than others.
Does having an affair make you a bad person?. Does a single choice define your life? Can a relationship survive the loss of a child? Can people find their way back to each other after doing terrible things to each other? I like the questions the show poses.
ETA: No excuse for the peanut butter thing. At all.
