We're going to split up.
This funny fandango we've been at for the last year (or thereabouts) is in stasis - not going forwards (to a 'proper' couple) or backwards (to 'just friends' again). It's stopped because she's indecisive, I know what I want, and have told her, but she's trapped between two choices, both involving an element of hurt, unwilling to bring any pain onto either of us.
So what must happen is that I will have to make the choice for her, and the choice is to split. In many ways such an outcome is ideal, she gets the decision made for her, and can feel like she's been wronged, I get to feel like the wise, all-knowing one and I can feel like I've been wronged too. It's just that it sucks.
