I am going against most of the replies you have had. Okay you had your son at 16 years old and brought him up well. You are still young at 36 and that is great in fact I had my first child at seventeen so not much difference in age from you.
My child however did not choose to make me a grand-parent when she was 20 years old but I damn well would have supported her and would have been happy for the news about a grand-child on the way.
Personally your line where you say " I have zero interest in this grand-child and want absolutely nothing to do with it" does sound harsh and selfish. This coming child did not have
any choice about being brought into this world and in fact is just an innocent part in this.
There are thousands of people in the world that have tried to conceive and have paid thousands for IVF and would give anything to be in a position to have a pregnancy also who knows what is around the corner this baby could be born and then something could happen in your family where for instance your son might not be able to father another child.
Walk away from a future with this child that is on the way
I would think differently if I was the person in your position.
When a political leader lies on their CV - can you trust them?
