The next step is critically important: Try not to, under any circumstances, engage in a deep conversation with her. If you do, will lose.
Right now you need to appear detached, unruffled and pragmatic. Convey that you don’t need her - at all. Don’t say that verbally, just convey that in your friendly detachment. No hard feelings, no drama. You need to be the ice man, but cordial.
This will be shocking to her, but her reaction is unknown. As I said before, she may be relieved, or she may try to “fix” things. One thing is for sure, though. She will respect you as a man.
