So selfish of her to tell him she was pregnant before the game
She knew it was the game of his life, that could have made his future. Yes, she hesitated when he pressed her for information, but she really just should have made something up about failing a math test or something and just let him play his game. And then after the game, she could have told him she was pregnant.
If he had gotten a basketball scholarship, he could have gone to college and still been with her to raise the baby together. It would have been much harder at first but better in the long run. Even if basketball didn't pan out, with a college education he would have been much better able to get a good job and provide for his family in the long run.
She really should have just not said anything. It just ended up blowing up his entire future.
