Yeah, sounds as if she is ashamed and wants all memories of what was gone.
I however would not let her treat me this way. When she is really off base with her remarks, you need to throw it back at her. It may be over and you may have lost her, but do not let her be so rude and make you feel so bad especially in front of others. BUT YOU SHOULD do this only to point out her rude behaviour, not to top bad behaviour with worse behaviour.
Sorry for how you are feeling.
