Ask April was right that, if you don’t want friendship but a date, you’ll have to stop being friends.
If you want to get out of it, ask her out on a date. If she says no, leave the friendship behind. Be civil, be flirtatious, but make her realize that you’re interested in dating, not friendship.
If she’s not ‘ready,’ don’t be ready to sit in the ‘waiting room’ either. Be the prize, not the backup plan.
