Of course it matters if she cares, and there is no proof she does not care, there is, as you named it, a rupture, which is a disconnect, a wound. These are part of all relationships, and repairing them strengthens the therapy, though I know it is very painful to be in the middle of one.

I am sorry she did not write back yet.

Perhaps you could email her once more asking for a brief acknowledgement and telling here how you are feeling right now?

Another option: what coping skills have you learned in the past two years? Writing here is a good one, what other things can you do to soothe yourself, to buy a little time until Monday? Monday's not too far, though it may feel like it!
