Re: need help with this girl at school
Start flirting more seriously and use push/pull. I would use statements like "Wow its great that you are _____, but I feel like we wouldn't work out." If she calls out "I never said i wanted you." just laugh and say "My point exactly." You have to increase the sexual tension before you make a move. So keep qualifying her by telling her why you two wouldn't work together while you escalate physically.
