I think you posted about this not long after the rupture and were very upset with her. It didn't sound like it ended well at all and that she was offering a way to have more of an ending, rather than opening the door to return. If I've got that right, then just be clear about why you're contacting her, and if it's to continue therapy then maybe share how your thinking has changed about therapy with her? And, for your own sake, be prepared for those same old feelings of anger and resentment to resurface if she doesn't respond the way you want her to.
