I'm sorry to hear that things with WG aren't living up to what you would like them to be, it does suck. One thing that I think a lot of us share are high standards, just by being here we have gained a fundamental understanding of what a healthy R looks like, how people in a healthy R should treat each other, and I don't think there are a lot of other people who have that knowledge. They tend to just wing it, causing them to be all over the place, which can be fun at times, but also can be frustrating.
I hope she can work through whatever she is dealing with (or has changed) and it becomes fun for you again. At least you know to, and are able to, step back and give her space, that might be the only thing that has kept "it" (whatever it is) from ending. Do you know if most of her past R lasted longer or less than where you two are? This could be a pattern for her.
