My ex has never contacted my son or laid eyes on him. I left him when I was 2 months pregnant due to abuse. I have my son bio dad's number I found on the Internet. Ds left a message on the voicemail, but never heard from him. Now my sin has passed away, but I don't feel obligated to tell bio dad because he never gave a shit about him when he was alive. My son was 19 when he died.
