When your spouse sees you’re feeling vulnerable, basically begs you to speak/act kinder to them and you not only refuse to do so-you amp up the hostility-that’s not some ‘personality quirk’ or sarcasm, that’s emotional abuse. Shane is like every insecure boy who wants to break up, but doesn’t want to take any blame. So, they just treat the girl worse and worse, trying to force her to leave first. Then, they can always have their trump card “You broke up with me!” He may have always been a little twirp with his comments, but in a marriage you can fake being nice for a little while when you see your spouse hurting. It’s not that hard. For someone supposedly so pious, he’s very selfish.
