For my part, I know how you feel. I'd want to ask about it and bring it up myself, but, IMHO, I think its important for you to let it go for the time being...as NYS says, its the actions that speak the most. Even if you ask, she may or may not confirm what you ask, and even if she does, she may be telling you one thing...etc. So, to keep it short, I'd just let her actions speak for themselves and see where it goes from there. If things continue to improve, then there will come a time when talking about it will be right.
"Achieve success, but without vanity; Achieve success, but without aggression; Achieve success, but without gain; Achieve success, but without force." Lao Tzu
