Using illness to control an ex
My partner's ex was diagnosed with cancer a few months ago. My partner found out through family, and has tried to be supportive. Now the ex has stated that unless the partner stops seeing me treatment will be stopped. Their relationship ended many years ago, we have been together for about 5 years but now can only stay in contact by phone, with no time frame in sight (who knows how long treatment will take?). The treatment so far has been surgery and is now adjuvent chemotherapy.
Is it normal to feel so angry and uncharitable about the ex? I am sorry about the cancer and stuff but does that mean I have to wait by the sidelines as a secret until they get the all clear?
