Good. I'll see if I can find that book in Kindle format on Amazon. I think some of the overshare is intentional.
A few years back, my sister took great delight in telling me that mum had had an affair and my parentage was in doubt. This is something I've never discussed with mum.
I was a bit freaked out initially, but then realized that there was nothing to b done. Mum is 79 years old. She shares more with sister than with me, which is fine.
No matter who my sire is, "dad" is the man who put his name on my birth certificate and raised me.
Another concern is that I am pretty sure she was drunk when she called me. She's an intermittent alcoholic...goes from drinking heavily to teetotal, periodically.
I might pick up some literature from Al-anon, as I have a REAL problem with dealing with drinkers.
