I have an idea for you, for whatever it's worth to you. You can try it or reject it:

Leave her alone for a while. Let her have freedom to do her behaviors without reacting. If she loves you, after not hearing from you for a while, she'll begin to miss you. If much time goes by without hearing from her, send her a little note through the regular mail. Just say, I miss you. How are you? And sign it: Love, (your name). And patiently wait for her to think & respond whenever she's emotionally ready. If you're lucky & you get another chance, show her how much you love her with kindness & let the relationship be an enjoyable journey for the both of you.
