Around his daughter:
The main thing for me is that IF his story is true, the situation must be fair, and the only way fairness can be sought is via court/legal process.
He wasn't told she was born until several weeks afterwards, he's been denied a paternity test because she wouldn't allow it, he should be contributing absolutely, but blindly because she says so? Absolutely not. Why would that be fair? For MLM supplements for a medical condition he hasn't got proof of and hasn't been told about prior? Fuck no.
If her family have refused him time alone with his daugther then that's unfair, if they are refusing to tell him if he's on the birth certificate that is unfair, if they are refusing to reasonably help him when he's clearly attempting to visit his daughter and contribute then that's unfair.
If all that is true then yes he's a victim, the same way we're victims when we get impregnated then left with nothing. Can we have some semblance of equality here please? Unfair is unfair, unless we're saying that because he's a man he should have less rights afforded to him, in which case c'mon please. Evolve.
But even if this is all true and he's been treated badly by this woman and her family, if the child is his, then simply paying towards school fees is a pretty tiny percentage of total costs, surely you can see that? Sure, something orderd by the court would be better, but courts in this country are terrible, do you really think it will be better in SA? Plus, he's not there? How on earth is any court ordered anything going to work? From a purely moral perspective, he has a child and that child generates expenses, including medical and school fees. I dn't blame him for wanting more proof of the cost or relevance of medicine... but more from the perspective of a loving and involved father. At the end of the day, if he's only paying towards school fees, I can see why when any new costs come up, this woman is asking him.
Also, I can't speak for SA as a whole here, but through DH's extended SA relatives, I can tell you that I've seen a lot of people who are dubious about things like ADHD and any kind of mainstream medication, and who are also very much into conspiracy theories. And I don't discuss DS' ADHD diagnosis with those relatives because of the batshit ridiculous things they say (also, my brother!) So it's possible that his child's family may be as conspiracy theorists as he is.
If he is one of the few farmers who have genuinely been kicked off their land and whose neighbours, friends or family have been murdered, I feel for him. But please note this isn't anywhere near as prevalent as some white south africans like to make out.
