Dude, leave it alone. Wait a few days. Stop having R talks.

Tell her that she is right about the D. You have decided that you don't want to be with someone who doesn't love you and you are moving on too. I haven't read all of your thread, but you have probably gotten all this advice before, right? Put it to use. No more pursuing. As hard as it is, you have to let her go and live for yourself and your D.

Hang in there man. Ignore her snide remarks.
