Depends on what you need to do for you

Where is your boundary

If she is in an active R with OM

It is up to you how and when you wish to communicate

She is not acting like your w

So you do not need to treat her like w

But you can be kind to her like a neighbor who is trying to contact you

If a neighbor I did not want to speak to did that

I might get back when convenient and say

Like Steve said what is up

Do not offer an apology for being slow to get back

If she immediately gets feisty

Feel free to end the call
