WAW and the law of attraction

[FormelyknownasF]

She's been contacting me to arrange the details on closing the bank account on friday. She's making this feel almost as if nothing had happened and we're just a married couple applying to get a loan.

She ends every message with "Is this ok for you?" "Thank you" etc.

I've been replying "ok" "no", etc. not more than 3 words.

I don't know how to read this.

Is she trying to be nice because in her eyes she's done nothing wrong so she's just ending this with "grace"?

or

Is she more at ease with what she did because she was able to see I'm fine ?

How should I respond to this "niceness"? I just don't want to take this as false hope.
