I imagine when he says he ‘lost’ in court he just means he wasn’t granted what he wanted. Cos she said something like she would only let him see the kid when she was present, so if he’s saying something like he wants the kid every other weekend all weekend (for example), and she’s saying the kid doesn’t know who he is so the court said no, in his eyes he ‘lost’.
I know a couple of men who were told they could only seen their kids in contact centres so they just opted to not see them at all… I imagine he has done the same.
