it seems like patience is something that she can't change about herself. I was very surprised this summer about how patient she was being. I had the girlfriend that I'd always wanted. I guess being that patient was extremely difficult for her, since she's now pressing me to hurry it along.
If this impatience is not a temporary problem, but rather a part of her character or something she's not willing/able to change about herself... you could choose to accept that.
Then the next question after accepting the lay of the land here becomes do you accept this about her AND still want to remain in relationship with her? Adjust your expectations of her accordingly and accept that some of your needs won't be met here?
Would the relationship still feed you in the way you need to be fed to make it worthwhile?
