Ok, so I need some help........

So me and one of my friends were playing match maker at school. I said maybe, MAYBE about one boy. I made it very clear I didn't want her to tell anyone. So then I mention it to one of my friends in front of her and she takes that as a sign to go around blabbering about it........

So then I started joking about a boy she said yes to, who is a total brat. Then she gets all mad at me, and then she just texted me saying she was sorry for 'being mad at me for no reason' and that she 'needs my help with something'................ what should I do?
