I lied to make her happy now what???

I said that the boy she liked, liked her back. And at Bingo Night tonight, she and her friend will ask him. I can't go to Bingo night to see what happens but *Lindsay* knows why *Jenny* hates me. So if they find out it's not true, then she'll make *Jenny* hate me more. I remember him telling me that he did like her, I'm just not sure if it's true anymore. Can I get someone to help me as "proof" that he does like her?
