Name changed as could be outing
I had son when I was 16 and his dad was 16. His dad wasn't ready to be a dad so I told him if/when he is to contact me and we could arrange to meet up. Son is now 5 (6 in December) and his dad has got in contact saying he wants contact with son so we met up at the weekend and son wouldn't go to him or speak to him. Son isn't shy so I don't know why he wouldn't.
His dad is upset and has told me to forget it then as his son doesn't want to know him and he's said he would be a terrible dad anyway.
Advice please
