Pure projection on her part. Her "feelings" not yours. Quit talking to her and when you do have to, make it short and sweet.
You can't do anything about the way she "feels". Focus on you and how to rebuild your self esteem. She basically has no respect for you right now. She is literally smoothing this over for herself, so she can justify her actions. It's not your job to ever punish her, but I think she needs to feel your loss.
Ask yourself, "what makes me happy?"
If she wants to walk away and continue a PA, then accept it. Be a man that KNOWS it is her loss and that there are 3 BILLION other women out there that will want to be with the new you.
All LBS's have something to own up to, but when you allow her to make you question yourself like this, you forget the fact she didn't have to cheat and she didn't have to walk away. Forgive yourself, cut yourself some slack, and GAL. Be someone that has self confidence and any woman would be a fool to leave.
You have to become the WAS now. Make her question why you aren't "being nice and THERE" anymore. Self empowerment, but not an excuse to be a jerk either. Just live your life like she's gone.
I wouldn't have thought of this advice, but this sounds really "right" to me - she is making herself feel better right now - she doesn't sound ready to own her stuff or even really see it right now - it's almost like to her, it's this nebulous pain but she doesn't know what - so she kind of jumped over it - skipped it. Maybe come back to it later.
Def. learn and grow from the input that she's given, but don't feel bad about it.
Feel good about your changes - to be independent - financially or whatever. Be grateful to her for the contrast that has helped you expand into this new version of yourself.
