But it does bother you, that's my point. And it would bother me too. There are so many why questions that come up and can send the LBS in an endless loop.
Saying to her that it doesn't bother you to hear from her is on the same philosophical ground of people saying 'I will always love you as you're the mother of my children' / 'I will be there for you as you're the mother of my children' etc etc. It communicates that you're okay being Plan B. I am not saying that it was your intention to do that at all, I am just saying how it can be perceived.
But more than that, you're not being honest and good to yourself by saying it doesn't bother you. You don't have to tell her to not contact you or anything, but stay true to yourself. Accept that it bothers you and then figure out how to move forward.
I will be honest and say that my approach to NC/Dark is on the tougher side of the spectrum. Any small crumb can get the LBS go down a spiral with no end.
I would rephrase whatever it is you're trying to do as - 'Is this going to help me in my healing journey?'
