If not, she may be having trouble moving from serial monogamy into polyamory. It may feel "unnatural". If that's the case, you might find that talking to her about the way you feel about each other and how she feels about her other relationship helps. Making friends in the poly- community where you are might help make things seem more "natural" as well.
If she has been successfully poly- in the past, it does sound like her feelings for you have simply changed, and you're going to need to decide what to do about the new, non-sexual relationship you now have.
I agree with jkelly..... very well said!!!
The key to life is in being fully engaged and peacefully detached simultaneously and authentically in each moment.
