How can i make him fall in love with me in one night?

i have been seeing this guy for a while now. we are very close and personal (sexually and emotionally) and i believe that i am in love with him. i have told him. he is stuck between me and another girl he texts 24/7 but doesnt see all the time. i have seen him everyday this summer. he is having a hard time picking one person, but says that he likes me a little more. as our summer is coming to an end, we will both be entering enior year together, the other girl will be a sophomore, and i am terrified our great connection that was thickened and built throughout the summer will go away. tomorrow night will be our last summer night together and i want it to be a night that will make him see im the one for him. i am planing on wearing a dress i know he likes. we dont go out, we usually stay inside, but how can i make him fal for me tomorrow night without acting like were already dating? i know i wont make him fall in LOVE with me, but just pretend like i could, what can i possibly do to make him never want to let me go.|||..You can't "make" anyone like you. You'll have to do it the old fashion way, get to know him.
