Background: My mother is a boundary-stomping narcissist. My childhood was tumultuous, we argued all the time well into adulthood. We have very little in common and have drastically different views on issues that are important to me, like politics, religion, and bodily autonomy.
4 or 5 years ago, I decided I was tired of having that kind of toxicity in my life and cut her out of it. I didn't give an ultimatum or let her know in any way - I just stopped talking to her. We didn't talk much at that point anyway, so it's not like it was suddenly noticeable.
Since then, I think I've gotten one Christmas card (with no personal message) and one email from her after my (paternal) grandfather died. I responded to neither.
My step-father was a casualty of the CO. We got along quite well when I was growing up and would have liked continuing a relationship with him, but I knew it would be a package deal, so he got CO too.
My social media accounts are basically as locked down as they can be and I've blocked both of them on FB, G+, LinkedIn, etc. as an extra step.
Now:
Mother dearest has finally realized I have a kid because I got tired of censoring my FB profile and header photos (there's no way to make those private). Now I'm getting FB friend requests from friends of the family and I discovered today that I had a message in my "Other" folder on FB from a family friend too:
"Please call your mother, she knows about the baby, she is heartbroken, she loves you and does not know why you want her out of your life and she has mellowed and children love her"
I think the very fact that he had to qualify that with "she has mellowed" speaks volumes to why I cut her out in the first place.
To my knowledge, neither she nor my step-father have tried contacting me directly. Maybe they sent FB messsages, but they're blocked. I've gotten no phone calls, emails, or letters at this point.
What do I do? Ignore this? Address it sternly? I have no interest in letting her back into my life, but I don't want it to escalate. I certainly don't want to answer the door one day to find her there. They never visited this house in the couple of years before the CO, but they only live ~1.5 hrs away.
