Ok so here goes my story. Basically, ive just left school and starting college soon. I started fancying this girl in year 9, i loved everything about her, and i was hoping we would get together someday. So i asked her out soon after that and she put it to me in a nice way that she wasnt interested. But after a year my feelings just didnt change at all, i was still mad on her, and she made it look to me like she was interested, so i got all my hopes up and asked her again, and to my dismay she said no. I was in tears for days, and then finally i seemed to get over her enough. I got a girlfriend about 3 months ago and things seemed to finally be going well, but complications happened in our relationship and it ended last month. Ive lost all feelings for my ex girlfriend, but im still madly hooked on the other girl. I told her she was the only girl i want in this whole world and told her how amazing she was but she just wont say yes and it makes me feel so

, and i just wonder what i have to do for her to want to be with me.
Now i could ask What should I Do, but...i think the answer would be...just forget about her and move on...but ive been trying that the last 2 years and it just is not working. So im all out of ideas here. Worst part is...im going to college with her, so im going to have to be around her the next 2 years of my life, seeing her going out with other boyfriends, and not being able to get her out of my head for another 2 years.
Im not sure what im asking...just...what can i do?
