Basically, she has to agree or not about a decision and she tends to agree but she is trying to agree.
She is in the stage of agreeing, accepting the situation.
How would you say it. She is in the stage of accepting the situation?
I'll suggest these but I will also suggest that she is not at this stage -- you're putting her at this stage with your belief that she should accept. She's really at the stage of decision, since she may or may not accept.
She is in the stage of acceptance.
She is in the point of acceptance.
