I'm currently writing a YA Fantasy about a young lady in her last year of high school who's feeling conflicted about coming out. She attends a party and finds out the girls there aren't all that interesting, and disappointed, she leaves. On her way home, she meets a girl about her age (around twenty although the real age is never given) and through a series of unusual circumstancs, they develop a friendship which ripens into love.
My question is, in the fast-paced world of literature, should I have the MC declare her feelings for the other woman quickly or wait until about halfway through? The other woman is open about her sexual orientation, by the way. I'm just curious as to how the more experienced writers out there would handle confessing one's feelings and would be grateful for any responses.
