Don’t feel like that.. no matter how much you teach someone, you can’t force them to use that knowledge.. I tried to take one of my young nephews that had quite a bit of problems and I could not help him. I ultimately had to make other arrangements because he was putting my own children at risk. I had horrible feelings about it but come to realize that you can’t force someone to accept help or believe in your beliefs. You can only guide them and hope for the the best. You did what you could and should be proud that you offered a chance. It’s not your problem that he chose not to take it.Oh and by the way if any of my family even bothered to talk to me you would definitely see something far better than family feud but we quit talking to each other years ago so...I just found out two days ago that the nephew that used to live with me has been drinking heavily and taking cocaine. He’s suspended from his job because he missed a day that he slept through when he was wasted. He lived with me for 15 years and he didn’t learn anything. Good thing I didn’t have any natural children. I feel like an utter failure.
