Wacky, the thing is, you really don't gE about stuff like this, even when you say you are gEing. There are lots of ??? in what is going on. Just to begin:
Your gf wanted to take you ring shopping and you were completely unaware. It would seem that your communications skills as a couple lacks a lot. I don't just mean a little, I mean A LOT a lot.
You have lived with a girl, just the two of you, for several months, and you claim to have never seen her or known her to poop. Would she say the same about you? That actually seems strange that you could live with her for several months and not be aware of her taking a dump.
Just trying to be real. I mean, poop is real. Buying a ring to get engaged is real. If either of these things are happening, then you guys should be talking about them, or at least be aware of them.
