My sad sad love life

Well it all started when i was in 8th grade i saw a girl in my class and she was really beautiful like,she should be a model kinda beautiful but she was secluded most of the time and had a group of just 3 friends. i am kind of a class clown so i usually went to their group and make fun of one guy(kind of a punching bag) and she seemed to like it,it wasn't that douchey kind of fun but just for laughes. so i was able to befriend her after that came 9th grade and i started to see her more because we were sitting closer in class,we became a closer and things kind of stayed stagnent in 10th because i thaught i was wayyyy out of her league and dident even wanna try,then in 11th(right now) her group kind of split up and she was all alone. i approached her and we started talking more i got to know that she was having problems at home her father was a big ahole and her mother and her brother were also suffering. i could understand her because i also went under that kinda phase for a while. she was a national level swimmer and dident like swimming. which was odd i asked her why and she said that she was doing it for her mother because she wanted it for her. she started staying depressed and often would sit alone if i wasent there, i told her that she should socialize with other people but she said that she dident want to talk to other people and just wanted to talk to me. i knew it wasent good for so i avoided her for a month i was hard for me but i did it, after a month i got news that she left school, i contacted her and confessed my feelings and told her everything she dident reject or accept just said "yeah i had a hint that you did" after a day or 2 i asked her out for a movie and she said yes but said that she would have to clear up her schedule due to shifting and that we maybe do it later, how do i make her mine??? =[
