My Dad (39) won't acknowledge his son (16). I am 19 and have been told my entire life not to mention my brother to anybody by my Dad and other family members. We haven't had a relationship up until about two years ago where we bumped into each other by coincidence and he approached me (as his Mum had only told him a few months prior). Over the last two years we have been seeing each other and building a relationship. My dad knows but not to the extent of how close mine and my brothers relationship is. My Dad lives 60 miles away from me whereas my brother lives round the corner. I have no doubt in my mind he is my brother as he looks exactly the same and my Dad refused a DNA test 16 years ago and has since married and had another child. His current wife doesn’t know about the child hence why I have always been told not to mention it. My Dad also coincidentally ran into him too, and decided not to acknowledge him. I asked questions about how he felt about it to which he gave a response of ‘it was weird’. He is actively trying for another child but in my mind I don't think it's fair for him to have another without acknowledging the 16 year old he already has. I want to do a DNA test with him to prove what I already know is right. AITA?

Edit: Not in U.S. 16 year olds mother chose not to pursue legal redress at any stage.
