When asked about me, do they ignore my existence? How do those instances play out?

It’s been 2 years since 7 of all my 9 family members stopped talking to me. Mom and only sibling sister included.

I always wonder to myself “surely, theyve met a stranger for the first time since then. Surely, theyve asked my mom if she has any kids.

Does she acknowledge my existence? Does she lie and act like we have a healthy relationship, to protect her image? Is there guilt in those moments?

Does she not remember my day of birth? Does she not remember the first time she held me? Does she not remember about the time she was most worried about me, whenever that was? Does she wake up thinking about me? Does she fall asleep thinking about me?

Does she care about my first child being born in 2 months?(confirmed by others that she’s heard thru the grape vine)

A son shouldn’t have to think these things about his blood family.
