Indeed, this might be the final straw. However, her doing her own introspection, her understanding needs she has when shit gets shitty can help her not repeat grinding on someone else than her partner. It can also help her clearly express what she needs in the future instead of taking hurtful actions. This part is on her though, it’s her own work she has to do on herself. The relationship being shitty is one thing, knowing what she needs is the next step. That’s how we avoid repeating dumb actions, knowing the why behind the hurtful things we do.

If he chooses to continue with her, she has to do that work on her. It’s tough questions one has to ask especially if she tells him she wants to fix things. How do we fix things if you don’t dig deeper than “I did this because we were doing shitty!”.
