I feel bad ignoring it, however, I haven't heard from her since our separation so I am kind of at a loss on how to proceed. I think she actually will be visiting WH right before her birthday
What did you all do?
It's really up to you how you want to proceed with your mother in law. I am NC with ex's whole family.

It also depends on your previous relationship with her. My former in-laws have stayed in contact with me, acknowledged my birthday, etc. They were great to me when I was married, and they continue to be kind to me and to reach out from time to time, so there's no way that I would purposefully cut off that relationship unless they did first or they were being hurtful to me.
