Why must everything be reduced to harsh, cold maths?
The human condition is quite incalculable.
It's hardly harsh, cold math. Math isn't cold and harsh, for one. It's really quite accessible, friendly and useful for a great many things. And it's just as good of a language as any to express the facts of life and relationships. Certainly as good as English at the very least.
If you think it is likely you will fail, or you doubt the value of SSY(Say Something, she says Yes), it's safer to simply cut your losses with SNY and SNN by merely getting over her. Trust me, this is how my love-life works, I know this stuff.
Trouble is, SN creates a lot of uncertainty, and for at least a few people invites long-term obsession and prolonged, terrible suffering. I had a similar problem not too long ago, and was just about ready to venture into Say Something territory, hoping that I'd get the SSN result and resolve the matter efficiently and effectively, but then realized that the SSY possibility, while remote and desirable at first thought, was nevertheless a possibility, and that I most assuredly couldn't be bothered to deal with it if it came up.
Granted, it's pretty easy to fix the game to most definitely get the SSN result and desired resolution, but that involves making a complete ass of yourself and deliberately sabotaging your love life, and if you're doing that, why even have a love life in the first place?
