I would feel very upset and take it very personally considering she can very well see others with OCD . I am also not a fan of abrupt terminations.

I would wonder if she really tried saving the relationship by means of consultation or educating herself more on the matter. These are valid questions to ask and I would probably send a letter expressing these thoughts.

The way this was handled wasn't in your best interest, I don't think so. Did she express any sympathy or regret? It doesn't like it to me.
