I don't think you are a jerk and as long as you were polite about telling here you felt hurt, you had every right to. One issue many of us have is trust and abandonment. It is possible she has not responded because she feels really bad. Remember we are all here with our own issues. However, it was good that you expressed your feelings to her in a non-hurtful way. Now it is up to her to process them.

Maybe send her a follow up note, just to say even though you were hurt you still value her and hope that everything is ok with her..... open the door but don't apologize.
Just a suggestion
