The point is You Are Good Enough. Sex is a sign of intimacy and when she chooses to be with someone else she is withdrawing her intimacy from you. She obviously wants more time. You have already made up your mind.
If you are asking why you are not "enough" for her ... well only she can tell you that. All your guesses are likely to be wrong cause she doesn't seem to understand them herself.
All your tapes may not be of help but if you only learn one thing from them... Don't impose limitations on yourself.
Take your power back and recognise you are good enough, always. When you believe you'll see it.
