I may have given the wrong impression. Things aren't great now, but they were really good before we moved in together. She's also had a rough couple years, and by her estimation isn't quite acting herself yet... so I'm not sure we'd be miserable together. I'm just not happy now and need time to see things change... but she doesn't want to give me that time because she wants to have kids soon.
Not to say that you're wrong... but I think I am interested in an open relationship and it might help us out as well.
