If anyone here is a guy finding themselves siding with the guy in this story, one way to "see things from the other side" is to imagine a scenario that is traditionally reversed in terms of gender roles. For example a scenario where your partner leaves hair clogging the bathtub and you have to clean up after them every time. And go buy drano and get dirty plunging the drain for 5 minutes every once in a blue moon. After repeatedly complaining about the issue for over a decade. "What do you mean I never clean up, I do my best to try to remember to do it. It's not a big deal. The pipes being old aren't my fault" they say every time. Be honest and tell me your immediate armchair solution isn't to bail out of that relationship.
